Bill Fang, a chemical engineer, started his career in the semiconductor industry but then made a move to the textile industry. A few years later, he realized that he is much more interested to restart his career in the semi industry and chose to join Nova as an Application Specialist.

Bill, can you please introduce yourself?

I went to Taiwan University, and I majored in chemical engineering. My thesis for my master’s degree was in a not very well-known field called: Super Critical Fluid. After graduation I began working at TSMC, which is the world’s largest semiconductor factory. Then I moved to another company that specializes in polyester fibers and that was a big change for me. After a few years, I realized that I am much more interested in the semiconductor industry and here I am at Nova.

Why did you choose to join Nova?

Two of my classmates work for Nova and have strongly recommended that I join. I knew that Nova, with 30 years of industry, maintains a young and exciting atmosphere where the people are kind and respectful to each other.

So, it’s very different from my previous company. It’s a different culture because it is a global company with a multicultural atmosphere. I also heard that the well-being activities are real fun. It’s very funny because I haven’t experienced that before in my previous company since they were a more traditional industry and now I am enjoying the attention and treats. My previous employers focused a lot more on work and not life beyond the job, like making friends at work. So it is a refreshing change. 

How was your onboarding experience so far in the few weeks since you joined Nova?

I have been at Nova for four weeks in Taiwan, and on my fifth week, I was sent to Israel for a month of training. I knew this would happen even before I joined and was excited to travel, learn and experience the Nova spirit. 

What Does your training include?

The purpose of the training is to learn about the physical principles of Nova MARS and how to use software to solve the customer’s problem. 

Are you planning to also travel during your stay in Israel?

Yeah, we have gone to the beaches in Tel Aviv where our hotel is located, and we are planning to visit the Dead Sea, Jaffa, and Jerusalem… Also, our colleagues in the service team have already invited us to have dinner with them, which is a very warm welcome. 

What do you do in your after-work activities?

In Taiwan, I like to go to the gym, exercise, and strengthen my body. And I also enjoy mountain climbing on the weekend because there are lots of beautiful mountains. There are about 200-300 mountains that we could climb in Taiwan. I love to do this with my friend, because I like the isolation from the city, from the work. We have no signal on our cell phones when we enter the mountains, and we take care of each other. I also like to train at the gym to get ready for climbing. Those are two of my main hobbies. And the most important thing, I got married last year. 

Oh, congratulations!

thank you!

Advanced algorithmics, machine learning, and “crazy” ideas: Nova believes in the strategic importance of software

An engineering failure in a building, whether at the foundations or in a brick in one of its floors, may lead to the collapse of the whole structure. The same is true for the field of computer chips, except that here the physical dimensions are less than one nanometer – a billionth of a meter. When the cost of every manufacturing error is the loss of billions of dollars, even the slightest component irregularity may disable the entire chip, cause tremendous losses, and disrupt a huge variety of products and services. At Nova, an Israeli company that offers leading inline metrology solutions, advanced hardware and sophisticated software are combined to solve this issue.

Leading semiconductor manufacturers use Nova’s measurement and monitoring systems, to minimize expensive mistakes in the chip manufacturing process. To support the growing demand for higher computation power and larger memory capacities, the Semiconductor development process is becoming more advanced and complex, requiring the measurement techniques to become increasingly more sophisticated.

“We support companies in the development and manufacturing process, conduct experiments, and use the data provided by the customer to form models,” says Dr. Danny Kandel, VP of Technology in the CTO group. “We are often required to develop unique and innovative metrology solutions, to support the development of new advanced integrated circuits. Since we deal with critically small dimension ranges which are difficult to measure, the measurement techniques must combine hardware, advanced algorithms, and machine learning.”

Dr. Danny Kandel, VP of Technology

Kandel is part of Nova’s CTO division, dealing with future technologies and focuses on the effort to solve future challenges in a rapid manner. Dr. Dror Shafir, VP of New Technology, in the CTO division: “for SSD memory chips, for example, we had to develop an optical technology combined with unique algorithms, able to measure complex signals, filter unnecessary data, and noise, and analyze the input aiming to provide an accurate representation to our customers. New innovative algorithmics, combining the conversion of scientific theories with complex mathematical models, were formed in the development process.

How can machine learning help achieve the best results with unique hardware?

The greatest ideas say Kandel and Shafir, arise when experts in different fields in the company brainstorm together. “Our clients require quick solutions for complex problems, and our way of overcoming these challenges is to get physicists, algorithm developers, and software experts to think together.” This, for example, is the reason why Nova started using machine learning as an alternative to traditional physics computations; “the machine learning applications we have embedded improved hardware performance, dramatically shortened the time required for highly-complex problem solution, and simply took over the market.”

The next step would be combining physics-based and machine-learning-based algorithms. “We have in fact created a new type of algorithm with distinct advantages of accuracy and speed, allowing us to solve problems which used to be unsolvable until recently.”  They both affirm that this innovative and creativity-encouraging approach, is deeply rooted in the company’s DNA: “whenever a team member comes up with a good idea, no matter how crazy or expensive it seems to be, everyone – from the CEO to junior directors – tells them to go for it, and it happened more than once. The potential impact of it is huge.”

Software Takes the Front Seat

Nova’s software group in the Dimensional Metrology division works closely with the algorithm, hardware, and system groups, and uses a wide variety of technologies to support the company’s growing product demand. “On the one hand, we offer traditional technologies that are at the core of Nova’s offering, technologies that we are constantly developing. On the other hand, we are adding top-tech software modules to keep up with the rapid development in our industry,” explains Kenny Krupnik, VP of Software in the Critical Dimensions Division, “We work with a wide variety of technologies and each of our development teams can offer a supplementary solution.”

Nova offers solutions of various types: software-hardware combined products dealing with the physical aspects of the metrology process as well as with robotics and communication, big data management products, tool-fleets management, software, and machine learning. “Historically, the chip market has been hardware-oriented, while Nova has an exceptional strategic approach of leading the market through software,” Krupnik adds. “For example, one of our flagship products, Nova Fit, is a leading machine-learning product that plays a major role in allowing Nova to meet its clients’ most strict measurement requirements. Our goal, producing advanced software solutions which will hasten the company’s growth, has proven itself during recent years, as the profit from these products showed significant growth.”.

Dr. Dror Shafir, VP of New Technology

“The chip industry stands is at the core of every other industry,” Shafir says. He states that the more complex the products get, the more advanced the chip and its manufacturing monitoring solutions must get: “we have to reinvent ourselves every time because we can’t just exploit more of the same thing, it just wouldn’t be enough.” Kandel adds: “if you look for challenges and openness to modern innovations, especially in the algorithmics field, with an open and supportive work environment, you will find it here.” And Krupnik sums up: “unlike most of our competitors, Nova’s size is optimal, producing a great combination of a strong, steadily growing company, with a progressive, family-like organizational culture, which allows personal growth and a never-ending technological experience. Things move fast and it’s a fun environment to work in.”

Right after graduating from her Master’s degree in Chemical engineering, Winnie Wang join Nova as an application specialist, not expecting that 2 weeks later, she would be traveling to Israel for a month-long training. Here is Winnie’s onboarding story.

Winnie, tell us a little bit about yourself.

 Sure, I graduated from National Tsing Hua University in Taiwan, and I majored in Chemical engineering.

I joined Nova a few weeks ago as an application specialist in the DMD and yes, this is my first job. 

Fresh out of college and only 2 weeks after joining Nova and you already traveled to the headquarters for a month-long training, Was it a surprise to you that you were going to start traveling so quickly after joining the company? 

Yes, it’s a bit nerve-wracking. So many changes in such a short time, but I do get to learn much in a short period of time and it is quite exciting.  Yet, I haven’t had a sound understanding about everything I am expected to do, I’m trying to learn quickly by digging deeper into it. This travel is actually a great learning experience and an opportunity to get to know colleagues in headquarters. 

Being so new to the company, what has been your onboarding experience so far? 

 My first impression is that Nova is a big family and everyone is very nice. Little by little, I’m getting used to it, all of it, and learning about Nova MARS, the product I will provide Nova’s customers, the technology, the atmosphere, and other important things at Nova.  The most inspiring thing here is that I can ask any question and I will get an answer to help me become more professional. Everyone here is so eager to help each other. 

What do you like to do in your personal time?

 I enjoy working out in the gym or at home, listening to music, and singing. I love to sing and my HR representative told me they might actually ask me to sing in Nova events. 

A singer and an engineer, what a perfect combination! What made you decide to join Nova? 

First of all, it is an international company, so I will have many opportunities to travel. I’m also excited to learn more about the semiconductor process and industry. So these were two appealing aspects of the job which are just the things I’m interested in for my career. 

If I was a student graduating, what would be your tips for moving from academia to industry?

My best tip for them would be: to join Nova. Although I have been here for a short period of time, I already feel it was a great decision to join. 

Where do you see yourself in Nova in 3-5 years’ time? 

I think I will have specialized in Nova MARS. I will have gained a deeper understanding of the semiconductor process and have efficient and professional skills to solve problems for our customers. And I think I will be in a leading position in five years. Of course, I need to work for it since this is my first job, so I need to invest and prepare for it more than others, especially at this point, I know very little about the industry. And maybe in three years, I will also get married.

Alon Palmor initially joined Nova's Elipson team as a mechanical engineering student. To his surprise, not only did he manage his time better, studying and working in the same time, he also improved his academic achievements. Here is his story

Tell us a bit about yourself, Alon.

My name is Alon Palmor, I’m twenty-nine years old, I’m originally from Ramat Gan, and I currently live in Tel Aviv. I joined Nova in 2019, as a student on the Elipson team, where I worked as a product engineer. I was with Nova for a year and half while I was still a student, and joined Nova in the second semester of my third year at university.

What did you study?

I studied mechanical engineering at Ben-Gurion University, in Beer-Sheva. Towards the end of my degree, I began working full-time as a product engineer, and that is what I do today.

How did you balance being both a student and working in hi-tech?

There’s a harder and bigger workload, that’s for sure, so I expected my grades to go down; but that’s exactly the opposite of what happened. Maybe it’s because being busy full-time suddenly gave me more perspective and more insight. It also gave me more practice for all the theories I was learning which led to my academic improvement. Suddenly my grades shot up.

Here at Nova, there’s an amazing team, and they’re always so happy to help. I had someone to consult with and ask questions about things I was learning. When something I had learned wasn’t clear, I would read a bit about it on the internet, then I would speak with an expert at Nova.

So contrary to my fears, joining Nova really pushed me forward in my studies. It also gave me a daily drive. Instead of being just a student who chose whether or not to go to class, I actually had responsibility. The responsibility helped me leverage my success both as a student, and as a professional, so of course, I’m really happy I had the opportunity to combine university and working in hi-tech.

How did you arrive at Nova?

I got lucky. I found a job with Nova very quickly. I was interviewing at another company at the same time that I was interviewing at Nova, and I was debating between Nova and the other company. Rosti Talis from the Nova Elipson team encouraged me to come. We served together in the army, in Unit 81, and he remembered me from there. He told me about Nova and I told him that I would love to hear more.

How did you feel about the interview process?

I don’t know if it’s like this for all interviewees, but the recruiting manager asked me to solve a real problem his team was dealing with. He said, “Look, we have a module we are working on and it has a problem, how do you suggest we solve it?” This was an interesting question because I was only a student and I had no idea what the company was working on. Although I prepared for the interview and read about Nova’s products online, I had to admit I had no understanding of what I was reading. Words which I use daily today were very foreign, then. Later in the interview, I learned that the interviewer understood how I was feeling, and he helped me and led me in the process. That’s how I realized and appreciated that he was testing my thought process and not my knowledge. I also connected with him as a person, which made me want to join the company.

It may sound weird, but I actually enjoyed the last interview (there were three). I had good chemistry with the interviewer and that’s what convinced me.

How did things develop after you graduated?

I really enjoyed my role in the Elipson team. When I got the product job, I was very happy, but I knew that mechanical design interested me, because throughout my studies the message that was conveyed was that mechanical design is more interesting because it deals with the mechanical aspect of the whole system. It’s a lot of geometry and planning how things will fit with each other, and I found it very interesting.

Throughout the year and a half of my job at Nova, while I was a student, I constantly kept wanting to get into the role of mechanical design. But, when I graduated and was in the process of moving to a full-time job, I was told there was no open position in the field, and I was offered a job as a product engineer on another team, Stand-Alone. I thought about it and realized that it could be interesting, because it’s also a role with a mechanical aspect, even though it’s not designed, or hardcore mechanical engineering. It’s a position that you can arrive at from different directions–electrical engineering, materials engineering, and more. I chose to accept the offer.

Today I understand how interested I am in this field–working on the system is a slightly broader direction, and it’s more challenging, in my opinion.

When you finished your degree, was it clear to you that you wanted to continue at Nova?

Absolutely, no doubt.

I didn’t even check other companies or even open LinkedIn to see offers so that I wouldn’t be tempted. There were a few reasons for this:

First, Nova is my place. I had a lot of fun in my work environment. Everyone is so nice and supportive, and they’re always ready to help you and teach you. Even before I had worked at Nova for a year and a half, I knew that I was in a very good place. I felt heard and knew that I was influencing the project through the things I was working on. It felt good that the project manager and team leaders consulted with me, and said things like “Alon, I need you on this.”

Second, I felt a lot was riding on me and that I had a real impact. I loved that.

Third, Nova’s conditions are good–from the facilities to the work-life balance. The work hours are very reasonable–this is something they work very hard at. If there is no real crisis, and there aren’t many of those, I won’t be asked to work late. In fact, if I’m working late, my manager will come and say “Alon, go home. It’s late.” This is something I really appreciate because in the army I worked 24/7, and while I enjoyed my work, I’m very happy to have a life beyond work, where I can maintain a routine and enjoy life.

Beyond all these things, I am able to grow and learn, and I’ve made friends here. All these things made me decide to stay at Nova no matter what.

Did you get to work with Rosti Talis after you joined Nova?

Rosti and I worked on the same team, so we got to work together. At first, I relied on him a lot. I felt very comfortable asking him questions and because he’s very smart and a very nice person, he knows how to explain things and make information accessible.

How would you describe the culture at Nova?

I talk about Nova to my siblings, my friends, and my parents, and they always respond by saying things like “Wow, Nova is a great place to work, or I want my son/brother to work there, or I have a friend to recommend…”

A lot of the work is done when people are happy and cheerful and there’s always teamwork and a lot of laughs and humor. At the same time, there is a high level of professionalism. When you put it all together, it makes Nova a very attractive place to work.

What do you do in your spare time?

I do a lot of sports. I love working out. I also love doing courses on Udemy, taking courses on self-empowerment, and expanding my general knowledge. I also play piano, unfortunately, I can’t bring a piano to Tel Aviv, so I visit my parents a lot, and I play there.

What advice do you have for engineering students?

Write your CV as early as possible and go to as many interviews as possible; even if you’re sure you don’t have time, and even if you have lots of tests. Just do it.

The reason to do it is that no matter what, you’ll learn, even if you fail. Job interviews require practice and learning. To be interviewed is its own thing that can be learned by having as many interviews as possible.

Before an interview, I suggest studying really well. Review a lot of theoretical material and Google all sorts of job interview questions.

Last but not least, make sure that the job you work at as a student, is in the field you’re learning. This is a great way to get into the industry because it’s much harder to find an entry-level position than it is to find a job as a student. Doing this will give you a significant advantage and time to learn. Nova was very considerate of my needs as a student, so I received a lot of free time and flexibility so that I could study for exams. I got to enjoy the best of both worlds and I highly recommend doing it.

Mandy Yong is Nova Taiwan’s Sr. HR generalist and Talent Acquisition Partner. Mandy has been with Nova Since 2017 and in this post, she generously shares 14 tips to help you nail your interview at Nova Taiwan.

Before Your interview

Do your research

Visit Nova’s website, google us, check out Nova Taiwan Facebook page, and learn about our culture, mission, and values. If you have a friend at Nova, talk to them to learn more. It’s vital that you understand our main business, our industry, our products and services, and who are our clients and competitors. The more knowledgeable you become, the more prepared you will be for the interview.

Demonstrate interest in the position

Review the job description, make sure you understand what it entails and how your skills, capabilities, and qualifications make you the right person for the job. If there are criteria you don’t directly meet, think about other skills or capabilities that you do have that you can apply instead. Yet, be realistic about any gaps in your knowledge and/or skills.

Get to know your interviewer

Ask who is going to interview you and then use LinkedIn to find out more about your interviewer’s professional interests and experience.

Prepare and practice

Ask a friend to do a mock-interview and help you prepare on a professional and technical level. Try to simulate situations with customers or tech issues you might need to resolve. Then prepare answers for the interview, how would you address these issues based on previous experience.

Here are some practice questions you can use: 

  • Why are you interested in this job opportunity?
  • What is your specific expertise?
  • Why do you want to join Nova?
  • Give us an example of a situation where you had to face a challenge with a customer/colleague?, how did you deal with it? What did you learn from it about yourself?
  • Give us an example of a stressful situation with a customer? What did you take from this experience about your abilities to deal with pressure?
  • Why did you leave/are you leaving your current position?
  • What would your ex-manager miss most about you when you leave?
  • How would your coworkers describe you?
  • What other companies have you interviewed with Is there a position you really wanted to go to and were not accepted? Why?
  • What is your current salary, and salary expectation? 

Be prepared to answer more challenging questions like:

  • Why is there a gap in your employment history?
  • Why have you changed jobs so frequently?

What to bring with you?

Make sure to bring 2 copies of your resume and other documents and materials you may want to present.

Relax. You got this.

Get a good night’s sleep the night before. Try to think about the interview as a conversation in which you’re coming to learn about the company. Thinking about it in this way can help your curiosity and listening skills shine through.

The day has arrived- What to do on the interview day? 

Candidate Interview at Nova Taiwan

Arrive 5-10 minutes early

First impressions matter. Arriving on time means arriving 5-10 minutes early. Remember your interview begins when you arrive at the reception desk. Be courteous and attentive.

Verbal and nonverbal communication is key

During the interview, answer with confidence, and stay positive. Be sure to smile and maintain eye contact as much as possible. Eye contact is an important part of nonverbal communication

Good listening skills go a long way

Making a good impression can be easy enough with a smile and a friendly greeting. Good listening skills can also go a long way in helping you to build rapport with the interviewer. Show that you are paying attention, listen more than you talk, and provide on-point responses.

Be curious 

Asking questions can show that you are curious, engaged and have great listening skills. It’s one more opportunity to create a great impression. Here are some questions you can ask:

  • What are the day-to-day responsibilities of the position?

  • What does the interview process looks like? What should I expect?

Saying goodbye

Say thank you with a firm handshake and a smile. You can even mention something that you enjoyed about the interview. This can help you be more memorable. You may also want to ask for the hiring manager’s business card, this will be useful for sending a follow-up email.

After the interview 

Following up

It’s a good idea to follow up while your name is still fresh in the interviewer’s mind. In your email, consider including one or two things you were excited to learn about, and any remaining questions you may have.

Meet Hanan Dor, a Customer Support Manager who relocated to Taiwan three and a half years ago. He shared with us everything you need to know about relocation, the best tips on how to prepare- and how Nova Taiwan made him feel right at home.

Hanan, tell us about you.

First and foremost, I’m the father of two girls and 1 boy, and I’ve been married since 2007. I’m an electronics engineer, and I joined Nova right after earning my degree. I’ve been with Nova for eleven exciting years. The first seven were in Israel, and now I’m in Taiwan. A few months ago, I was promoted to Customer Support Manager.

Relocation seems like it can be a challenge with a family. How was that for you?

Yes, relocation can be a challenge. For my family the issues were mostly about the kids, making sure that they have a smooth acclimation process, and taking care of their emotional well-being. When we first got to Taiwan, my youngest daughter was three months old, and my other two were five and seven. My seven-year-old just started second grade here, and there were multiple challenges of moving to a new place, a new school, a new language and a new culture.  

To make the kids feel at home, my wife began cooking the foods we were used to from home and traditional Israeli foods on holidays. Since moving, we began to use food to keep the connection to Israel and to feel more at home.

How did the folks at Nova Taiwan welcome you?

The truth is, that from the moment we got here, everyone was amazing; Maggie, Mandy, and everyone who helped us. They were very helpful with any problem or things we didn’t know, like how can we receive packages from home, or where to buy food, and they would constantly ask me if we were okay, if we need anything, and if there’s anything they can do for us. They really went out of their way to help me with everything from the kids, schools, medical issues and even things related to the Jewish holidays.

And while I could never repay them for their kindness, I tried very hard to show them my gratitude. So on Channukah, my wife made sufganiyot (Jewish doughnuts), and I brought them to the office. On other holidays, I did my best to share experiences from my culture with them.

That’s heartwarming. Do you think this type of culture is why people stay at Nova for so many years?

Nova is very welcoming and supportive. Throughout my years at Nova, my managers have always been attentive to my needs. I have had many meetings with managers who are two or three levels above me on a monthly, quarterly, or annual basis, and they’ve always done their best to help me with everything.

It’s very clear that at Nova, managers are going above and beyond to retain talent. You’re given the feeling that you matter. 

Today, as a manager, I do the same. I will do my best to give valuable feedback. If something is not working for my team member, I will do my best to help them shine, like changing their role to something more suitable. And if I can’t keep them in my group, I’ll look for another group, but always within Nova. It almost never happens that we can’t retain someone.

Israeli culture is so distinct. How did you deal with the cultural differences?

On a professional level, there was definitely a challenge, and I knew there would be; that’s how it is whenever you conduct business in a different country and there’s a culture gap.

In Taiwan, people are hard workers with high work ethics and are very polite. Israelis are very open and sometimes their communication style can be blunt, while in Taiwan they don’t always tell you the harsh truth, out of politeness. I learned to ask a lot of questions if there was something I needed to understand.

In that respect it’s challenging. But I managed to break through with small daily efforts. I did my best to help my new colleagues with all sorts of things that were important to them. And when you show up like that, you end up growing on them and gaining trust and even friendship.

Did you feel like you finally got “in” with them?

When you relocate, it’s important to remember that you’ll always be a  foreigner. Because even though you live and work with the locals, and maybe even speak their language, they will always be cultural nuances, and it’s important to keep it in mind. Having said that, once I managed to gain the team’s trust, it made it easier for us to connect and I hope it will also make it easy for the people who will relocate to Taiwan after me.

What helped you gain the trust and friendship of the team at Nova Taiwan?

Apart from being helpful where I could, supporting the team members in their requests, I also created relationships all over the levels -;. it’s important to be connected to the local day-to-day activities as well as culture. At the same time, I tried to connect with them as well thru my holidays. I feel that when you share your personal life it helps gain trust and make authentic friendships with your Colleagues.

It took me about a year and a half to build these relationships, yet the effort was worth it.

What characterizes your management style?

I let everyone run ahead with what they’re doing. I don’t micromanage. I personally have no time for it, but I also believe that there is nothing good in managing people that way because it can drive them crazy. I speak to people in terms of our processes and our products, and then make sure they know that I trust them and their judgment.

I tend to delegate a lot. This helps me take a lot off the load, but it also helps my team members grow to become the next generation of managers and team leaders. By delegating authority I’m able to build Nova’s future generation of managers.

Julia Hoffman, PhD, is an Algorithm Technologist in our material’s metrology division.
Julia loves writing algorithms, but she also loves the variety that her position enables.
In our conversation, Julia shares her superpower, what attracted her to Nova, and her best advice for young women who want to pursue science and a corporate career.

What’s your superpower, Julia?

What a fun question! I have the ability to visualize the results of a physical experiment.

When did you know that you wanted to study physics?

As a kid I wanted to be a vet. I was raised with cats, dogs, hamsters, birds, fish – you name it.

But I was also always really interested in how things work. When physics was introduced to me, I finally found so many answers to questions I had. This is when my future began to take shape, even though I didn’t know it then.

As a kid in school, I always excelled at physics. It came very easily to me. But later on, in university in Poland, I had to choose a major in the type of physics I wanted to study (medical physics, solid-state physics, elementary particles, nuclear physics, etc.).

Do you have any idea how hard it is to choose just one field, when you want to know everything?!

I chose elementary particles, and I think I made a great choice. It’s an awesome part of physics, and it enabled me to participate in the Higgs Boson discovery. I analyzed data collected by the most awesome elementary particle detector in outer space (AMS-02).

Now I’m discovering the world of semiconductor metrology. That all would not happen without the elementary particles specialization I chose at university.

What attracted you to Nova?

Opportunities to work on various projects. During my interview, when I talked with Heath, our Algorithm Director, he asked if I’d be ready to actually participate in taking measurements on a tool. I wanted to sound super-professional and said “yes, of course,” but inside my head it was like “Yesss!!! Yesssss!!!! Pick me! Me! Me! I want the job!”

My main job today, is creating algorithms to help process, quantify and understand data. But to do it well, I want to know how the tool works (see the pattern?). So first I want to get familiar with the tool to learn how it collects data, how the data is created, what its impact is, and how the software works. So I work with Bruno, our Principal Scientist, with system engineers, software developers, and application specialists. They let me learn, and do hands-on projects. I’m not confined to just writing code. I get to know a bit of everything, and I love it!

What was the best advice that you ever received? How did it help you?

“Reach for the stars – the worst thing that may happen is you will get to the Moon”. And I’m working on it. For me it takes a lot of work to believe in myself. But I have wonderful friends and they help. So I’m reaching for the stars

What do you love most about what you do?

The variety of tasks, the opportunity to keep learning, and the anticipation of awesome projects just around the corner.

Nova is my first job in the hi-tech industry, after years spent in academia. I feel so appreciated at Nova. This is a dream place for me to be, I love it here!

What are you most passionate about, outside of your working hours?
I love everything outdoors and mountain climbing is my most favorite thing to do. During the COVID 19 lockdowns, I couldn’t do this, so I developed a passion for growing tomatoes on my terrace. BUt mountain climbing is my first choice.

What advice would you give to young women who want to pursue science and a career in the corporate world?

Believe in yourself, get help from friends, your spouse, and colleagues to build your confidence. Make sure to try new things, celebrate your success, and simply know that you are good at what you do. And of course, don’t forget to “reach for the stars – the worst that may happen is you will get to the Moon.”

Olga Krasnikov, Nova’s Modeling R&D Application Manager has been working for Nova for more than eleven years! We sat down with her to talk about Software modeling evolution in Nova and gained bonus insights about team leadership and motivation

Eleven years is so impressive, Olga! What influenced your choice?

I joined Nova, fresh out of university. I studied physics at Ben Gurion University and today I hold a BSc in Physics and an MSc in Electro-Optic engineering.
When looking for a job, after graduation, I sent out a few CVs and interviewed with several companies. But I decided to place my bet on Nova, because I liked the atmosphere. So here I am, eleven years later, and still going strong.
The manager that recruited me, Avron is still here as well. He is no longer my manager, but we still get to work together a lot. When he has special requests or critique, I like to joke with him, that if he doesn’t like my work, it’s his fault, because he made the decision to hire me.  

Since you came to Nova, you’ve held in quite a few positions. Can you describe your journey?

I started at Nova as an application engineer. This job evolved in the direction of R&D modeling, and then grew to team leader positions in the R&D applications team. About a year and a half ago I started managing a small modeling project and since then, I received two additional software modeling projects, to make life a bit more interesting.  

From your experience as a manager, do you think men and women have different managing styles?

I reject the idea that women and men operate differently because of their gender. I know different people have different management styles. But in my opinion, the different styles can only be attributed to the managers’ character, attitude, and persona, not to their gender. It is all about personal traits and attitude. 

What motivates your success?

I have a personal drive to complete my projects successfully. This doesn’t mean that all my projects in the last eleven years were successful. But I am driven by my need to bring the projects I work on to successful completion. My second driver is my need to keep things versatile and interesting. I really enjoy the action my work provides. 
I love it when I get a project in its nascent stages. I get to grow the metaphorical baby into a full product that our customers actually need and use. 

Can you share your insights about motivating your team?

Sure. I believe it’s important that the team is connected to the goals: I make sure they understand what unique value the project brings, who is the customer, and what are the milestones. This helps ensure that we are keeping our priorities straight – once all team members are aligned with the goals, we can start operating as a team. In addition, I’m trying to get as much feedback as possible from the end-users and bring them to the R&D team. Or even bring the internal end-users into the R&D process as early as possible – this creates the difference between a good and an excellent product.

What successful project are you most proud of?

Oh no, I’m really terrible at this. ???? All the successes that I’ve had, were the result of teamwork. It is never just about my success. It is never ever my own success.

I’m not going to let you off the hook that easy- Let’s rephrase. If I were to ask your colleagues what they think about you professionally, what would they say?

You’re not really asking me this.  I guess they would be positive about my work. But again, I feel like I’m doing my job, and there’s nothing really special about the things I do. The quality of my work, my motivation, my dedication – they’re exactly the same as my colleagues’. If you really want to know what my colleagues think of me, just ask them.  

I love that idea. We will ask your colleague Michael Shifrin to share his opinion of you… 

What makes you proud of working at Nova?

While I do not attribute the success of the modeling products to me, but to the whole team, I am very proud of the growth in this area, in recent years. When there is a challenge, and it doesn’t matter if it’s technical or commercial, the entire team contributes to finding a solution. 
The team comes together, bringing with them their entire selves – their motivation, skills, knowledge and a multidisciplinary approach, to help resolve the issue. It is really beautiful to see the growth here, which means were doing something right. And it makes me very proud to work here.

What are the 3 best things about working at Nova?

  • I enjoy working here because of the people. Even when we were able to work at home, I came to the office. But I like the people here, on a personal level, and I appreciate them professionally, so it makes sense to me that I make the effort to come into the office. I really enjoy working with them.
  • Technology! I think Nova does really great things. We have a comprehensive portfolio, and this allows us to put the focus on the important things, and offer better solutions to our customers
  • There is great synergy between the various teams. Yes, there are conflicts of priorities, but everyone makes their best effort to make things happen and support the needs of other teams.

A good advice from her high school teacher lead Marla Fields to make a life-changing choice about her academic path. Today, Marla, Sr. Project Manager at Nova's Material Metrology Division, passes this on, as she mentors' coaches and inspires young girls to fulfil their true potential

Marla, give us a little background – what do you do at Nova?

My name is Marla Fields and I have a bachelor’s degree in chemical engineering from MIT. At Nova I work as a senior technical program manager and I Focus mostly on Nova Metrion in the materials Metrology division. I work on multiple projects at the same time. I get to be a part of a lot that’s going on at Nova.  I’ve been working at Nova for just under a year. 

How was the onboarding process for you? what stood out for you?

One of the big things for me when I got here, is that when I asked questions, everybody was really helpful. They wanted to give me as much information as possible that could help me in my role. I would ask for an inch and they would give me a mile of information. At the beginning, it was almost like drinking from a firehose. But it was super helpful to get me up to speed really quickly. It also helped me understand not only what we were doing, but also why we were doing it. Nobody ever asked me why I needed to know things. I felt like a part of the team from the very beginning. Everybody just wanted to help me be as successful as possible, and they weren’t worried about why I needed to know, or how I was going to use the information – the culture is very different than other companies I worked at in the past. I found it really refreshing to be in a place where everybody wants everyone to succeed.   

Wow. That’s really beautiful to hear. What made you decide to join in the first place?

I was looking for a job during the pandemic, and I interviewed with several companies. But it was at Nova that I had the most interviews, and where I got to speak with the most people. At some other companies I had something like five interviews, and they gave me offers, but it didn’t feel like I met very many people. When it came time to make a decision, it felt like I had a really good vision of what Nova is and what the people are like, because I had met so many people. It also helped that a colleague who worked at Nova, suggested I apply. Another person who helped me make my decision was my husband.

He said to me “do you realize that you’re always really happy after you’ve talked to people from Nova? That you’re happier about those interviews than about other interviews?” And he said, “I think that needs to play into your decision.” So, my husband was a huge advocate for Nova. Even though he wasn’t a part of those interviews, he could see how the interviews affected me in a positive way. 

Family members are such a huge part of our lives. Do you feel Nova share’s that view?

Most definitely. A few months ago at Nova’s summer family events here in California, I couldn’t bring my husband because he’s an essential worker, but I brought my five-year-old, and my mother who is seventy-eight. I think my son has a crush on Dean Hunt, my boss and manager, because he went swimming, and Dean was throwing him in the pool. When he came out for a popsicle, he didn’t want me or granny to taste it. He just ran over to Dean and was like “Dean, I got a popsicle!” He was so excited. And then there’s my mother, who I care for. She has health issues. Nova has been just amazing. When you’re taking care of someone who is elderly, and who lives with you, it can get complicated.  I’m seeing a different doctor with her almost every week because we have to make important decisions regarding her health. Nova has been very supportive about it, nobody has ever gotten upset because I had to take her to the doctor.

You certainly have a lot on your plate – your career, your son, your husband, and mom whom we hope will be well. Does that leave you any time for yourself? For your own hobbies and interests? 

I always find the time. I actually have something tonight. I’m a board member of a nonprofit called Girls on the Run Silicon Valley. I’ve been a board member since 2017. This past year has been really tough with COVID, because we couldn’t have a lot of activities. As a board member we’ve had to make really difficult decisions: how do we keep people on our payroll? How do we continue to provide services going forward?

A lot of nonprofits have gone under, and I feel so fortunate that we were able, despite various restrictions, to continue our activity and keep the paid employees of the nonprofit, on the payroll. I think we did a really good job with great leadership and our executive director. So we’re going to come out of this, and we’re going to continue running programs, which is amazing.   

What does Girls on the Run Silicon Valley do? How do they help girls?

The goal of the organization is to raise stronger girls; girls who are more self-sufficient and confident. They do this by creating running programs, where at the end of the program, which is typically ten or twelve weeks, they run a 5K. During COVID, we did this virtually, and while we did manage to do an in-person event, we couldn’t do a big event. Normally we’d have around a thousand girls. The program is about finishing a 5KM run, not about how fast you finish. It’s about always moving forward. The program also focuses on teaching girls about bullying, how to stand up for yourself, how to take care of your body, and that you’re worth it. And though it’s not STEM related, minorities and STEM are my passion, so I think that strong girls make the best engineers, and I just love the program. I’ve been working with Girls on the Run Silicon Valley since 2009. For three years I coached the girls, I then did other volunteer work for them, and in 2017, I joined the board.

I also do a lot of speaking engagements because I believe in getting women and minorities into STEM. Recently I was at Girlstart – they do summer and afterschool programs for girls, and I spoke at one of their camps about what I do and what I’ve done in the past. I also volunteer with the Greene Scholars Program, I volunteer with them a couple of times a year, as a science fair judge. I’ve also worked with TechBridge and Breakthrough. Because I’m a black female engineer, I feel like they need to see people like me being an engineer.

Absolutely. You are an incredible role model of what’s possible. Thank you for everything you’re doing. Do you have any hobbies you do to have fun?

I like to play softball. I have a softball game next Monday.  

What led you into the field of chemistry?

I actually didn’t know what I wanted to be for the longest time. When I got into college, I had to choose between MIT and Dartmouth, and I didn’t know which one I wanted. All my teachers and everybody told me “oh, go to MIT. MIT is the best in the world, you should go there.” But I was just like, “but what if I don’t want to be an engineer? What if I want to study Spanish? Then MIT isn’t the place for me, and I should go to Dartmouth, right?” My PE teacher is actually the one who helped me make that decision. He pulled me aside while forcing me to run laps, and he was like “Marla, you’ve grown your entire life and always lived in rural New Hampshire. This is your chance to go live in Boston, live in the big city, and not be tied to it. And if you hate living in the big city, you can always come back, but this is your opportunity.” And I was like – that is the best idea ever.

Because it wasn’t just about MIT being a good school, it was because I’ll learn something about myself. And so I ended up going to MIT. And I didn’t know what I wanted to study. I actually went into my sophomore year as an undeclared sophomore. I couldn’t stay with my freshman advisor, as he was leaving the institute, so I ended up in the Dean’s office, because she had to find a place for me. She told me “you can’t be that undecided – you have to know what you want.” So I told her that I was debating between chemical engineering and math. And because I always make decisions based on practicality, I chose chemical engineering. That’s because she told me that chemical engineering has more requirements than math. And that if I decide on chemical engineering, but I switch to math, I’ll still be able to graduate on time- but not if I did things the other way around. Practicality won the day I chose to be a chemical engineer.

What do you enjoy most about working at Nova?

Good question. It may change over time, but right now I absolutely love working at Nova because I love the people I come to work with. It feels like everybody wants to move forward and that they want to move in the right direction. They might not all agree what that direction is, right? But it’s clear that everybody is coming from a good place. Everybody is coming from a place of wanting to move the company and the products forward, and put their best foot forward.

As a program manager do you still get to work on tools?

At a big company like Applied, my previous employer, I didn’t. But because we’re a smaller company, I get to go into the lab, and sometimes when the guys need help, I’ll help them. I have packed up controllers when we shipped controllers because there was so much to be done, and not enough hands to do it. I’ve spent hours helping the guys clean tools, wiping things down and cleaning things up before shipping. That’s another plus for Nova.

So you literally get your hands dirty.

Yes. We just brought one of our tools in and I got to drive the air bearings. I like being able to be in the lab and do the dirty work, as well as set up the meetings. 

What’s one thing your teammates don’t know about you yet?

I don’t think that they know that I play softball, because it hasn’t started yet. So they don’t know that I play competitively in a women’s league. We play tournaments on the weekend, sometimes. We played in Las Vegas right before COVID hit. I also don’t think they know how good I am during a crisis. Because my mother has been living with me for almost fifteen years, I’ve seen a lot of crises. I am trained at CPR and first aid and I’ve kept up my certification for about two decades. I use it more than one might think. So I’m the one you want in your corner when something goes down. 

I definitely want you in my corner, because there are always challenges.

Exactly. There are always tough things to do and deal with. Right now, we’re trying to get a tool off the ground in China, and we can’t go there ourselves, but yesterday we were successful! We managed to set up a laptop and for the first time we got to see the guys from China in the lab. I almost wanted to cry.

It sounds like you’re the type of person who needs to keep pushing through projects, and if you don’t get there, you’ll still find a way to get there.  

That right. It’s kind of the way I’ve dealt with everything in life, by just taking one step forward. If you can just take one step forward each day, you’re already better off than you were yesterday. You may not be where you want to be, or where everybody wants you to be at that point, but if you are still moving forward, then you’re doing all right in my book. It’s the best thing you can do, and it’s the best thing you can hope for.

What do you do when things get difficult and you feel overwhelmed? Does that ever happen?

There are a lot of times in life when things get kind of difficult. When that happens and I feel overwhelmed, I focus on the small things, and one of those little things each day that did go right. I have a gratitude journal, and I make sure that I write in it every day. I actually was looking at it the other day and I saw entries from when I was interviewing at Nova. It’s great to be able to look back when you’re having a tough day and remember good moments. Things don’t seem as bad.

Dr. Shay Wolfling, Nova's CTO is proud to introduce the Nova Metrion®- our new in-line SIMS product and technology.

Click Play to watch the webinar

Hello to you all, In this short online Webinar, I want to introduce the Nova Metrion®– our new in-line SIMS product and technology.

The webinar will include a short overview of the technology, a few typical use cases, and some of the product highlights.

I’m Shay Wolfling, Nova’s CTO, responsible for our technology development for the past 10 years.

Nova Metrion

Following the press release we issued, we are happy to announce Nova’s new Material Metrology solution – the Nova Metrion®.

The Nova Metrion® platform is based on the technology of Secondary Ion Mass Spectrometer (or SIMS), which is widely used today in semiconductor laboratories.

SIMS is used to measure complex logic and memory stacks and obtain precise depth-profiles of material properties.

The uniqueness and innovation of the Nova Metrion® is by bringing this advanced technology into the fab. This enables in-line SPC, in a fully automated way on 300mm production wafers.

Materials Engineering

The Nova Metrion® expands Nova’s solutions to the growing challenges of Material Engineering.

Beyond scaling and 3D architectures, customers are introducing new materials in each new generation, and the industry increases its reliance on materials engineering to advance performance and scaling.

These changes create a greater need to monitor and control advanced materials, and increase the demand for new measurements to precisely characterize minute changes in material properties.

Materials Metrology Portfolio

The usage of new methods for materials engineering is reflected in the growth of both our Xray and Optical material-metrology solutions.

Our XPS Nova VeraFlex tool for controlling composition and thickness of ultra-thin films has already been adopted in-line by all leading device makers.

The recently introduced Raman-Spectroscopy based Elipson, has also been adopted by leading memory and logic customers, running accurate in-line measurements on production wafers.

The Nova Metrion® is the newest addition to Nova’s Materials Metrology Portfolio:

  • Expanding our application coverage to include material-composition depth-profiling
  • and expanding our technology offering, to include Ions as well as X-Ray and Optics.

SIMS Technology

So, what is the SIMS Technology and how does it enable obtaining precise depth profiles of material composition?

  • We use a focused ion beam to remove minute layers of the wafer.
  • Charged ions of the extracted material (named secondary Ions) are collected and analyzed by a Mass Spectrometer, having multiple detectors that can detect different materials in parallel.
  • We thus get a full concentration and depth distribution of specific elements through the wafer- stack at the point of measurement.

Let me give one specific example:

  • This output graph shows the composition of a SiGe:B EPI wafer. Boron, Germanium, and Silicon are detected in the EPI layer.
  • The different colors show the change in concentration of the different materials as a function of depth.
  • This measurement can be repeated at several locations on the wafer, to create a wafer map.
  • The change in concentration as a function of depth is then uploaded to the factory host, where the data is monitored for process control.

As the measurement area is very small and as the source is contamination free, the wafer can go back into production to continue its manufacturing process, making Metrion a true in-line metrology tool.

Application Space

In-Line SIMS has a variety of high-value applications to significantly improve process control of critical steps.

Here we have 3 examples:

  • Monitoring material doping concentration in the Epi process.
  • Controlling the uniformity of Silicon-Germanium deposition in Nanosheets.
  • Detecting critical contaminants in 3DNAND manufacturing.

These use cases have been validated by customers and some are already running in production.

Dopant Concentration

The first use case I will describe is monitoring the doping or concentration of Boron, while epitaxially growing Silicon-Germanium layers. Since very small variations in the Boron concentration can impact the final device performance, Metrion platform is used to qualify, monitor, and match Epi chambers in the Fab.

During the Epi process, Metrion is used to control some key parameters:

  • Monitoring Epi growth uniformity, by tracking the Ge concentration and the ratio of Germanium to Boron (referred to as “Ge fraction”).
  • Measuring the Dopant concentration profile, peak concentration, and uniformity across the wafer.

On the top graph you can see an example of a single measurement of Boron, Germanium, and Si concentration profiles.

On the bottom graph you can see the tracking over time of the average Boron concentration and Germanium fraction, as being sent to the fab host for automatic SPC of the Epi process.

As a result of chamber qualification and matching in the fab, customers can achieve tighter process control on the challenging Epi process and higher uptime to their Epi chambers.

Deposition Uniformity

The 2nd use case is controlling the uniformity of Silicon-Germanium deposition in Nanosheets.

One of the critical steps in the manufacturing of Nanosheets or Gate-All-Around, is the deposition of SiGe.

The concentration of the Germanium, and in particular its uniform deposition on each nanosheet, dramatically affects the selectivity of the following etch process and has direct impact on the electrical performance of the transistor.

In-Line SIMS is used to monitor within-layer and within-wafer uniformity:

  • On the bottom graph you can see the Germanium concentration variation across each one of the 3 individual Nanosheets in one specific location.
  • While on the top graph you can see the uniformity of the Germanium concentration across the entire wafer, based on 9 measurement points.

Contamination Detection

The last Metrion use case I will review is Contamination-Detection in the deposition of the Word-line in 3DNAND.

Fluorine and Chlorine, which are materials used in the deposition of the Tungsten metal layer, tend to diffuse into the dielectric layer and can kill the device.

With in-line SIMS customers can detect and measure the concentration of these deadly contaminants through the stack.

On the top graph you can see a Metrion measurement result of the concentration profile of Chlorine and Fluorine.

On the bottom graph you can see an SPC chart example of monitoring Fluorine within spec over time and the beginning of a process excursion where the Fluorine Level increases beyond the upper control limit.

Measuring these contaminants in-line is critical both for improved accuracy as well as for device yield. Sending wafers to the Lab takes too long to detect, putting many wafers at risk before the process excursion is detected.

Uniquely designed for HVM

One key point to note before I summarize:

Nova’s Metrion implementation is very different from a Lab SIMS.

The platform is a fully automated, recipe-driven, 300mm wafer metrology system that seamlessly integrates into a Fab workflow for wafer-level analysis.

From an architecture perspective, the Metrion is designed from the ground up for the production environment:

This unique architecture is reflected in many key components including contamination-free advanced source, and a novel detector technology, which can measure multiple materials simultaneously.

The innovative architecture and differentiated components result in superior depth resolution as well as stable and repeatable measurements.

The system performs the analysis on a small measurement area, compatible with production wafers.

Combined with state-of-the art data analysis, the Nova Metrion® provides quantitative and actionable results, enabling advanced process control of complex and critical multi-layer films.

Summary

To summarize this Webinar:

  • We are proud to launch the industry’s first In-Line SIMS, enabling SPC of material composition profiles within Semiconductor production lines.
  • The Nova Metrion® is a fully automated HVM-worthy platform, with unique architecture and data analytics, targeted for the process control of complex 3D logic and memory stacks.
  • The output is high quality, reliable and repeatable SIMS data.
  • The Nova Metrion® is already installed and running in multiple locations, and Nova is expected to recognize revenues from this platform during 2021.

Nova Metrion® is the latest addition to our growing portfolio of advanced materials metrology solutions, bringing better process control to our customers.

This concludes today’s Webinar.

Thank you for attending.
