Mechanical engineering


In a nutshell


Veldhoven, Netherlands


Research & development



Job Category

Physics, Mechanical engineering, Mathematics


Are you a master student in Physics, Mechanical Engineering, Applied Mathematics or similar? Do you have a background in Control or Chaos Theory and an affinity with Physics Modeling? Then this internship could be interesting for you!

Background information

Life of ASML’s machines begin after they leave their birthplace in Veldhoven. They are subjected to workload and elements around, their precision is so high that changes in the performance can be observed just after several days of work. The Metrology and Machine Control Development and Engineering department is responsible for controlling the state and performance of ASML’s EUV systems and ultimately to keep their precision over their lifetime.

In more detail, the stability of ASML’s machines, TwinScans, is controlled over time using a set of parameters called the Scanner Baseline Constants. A new set of such parameters is usually calculated every 3 days. Their evolution is a result of changes in the internal state of TwinScan. For example, due to physical degradation of some hardware components or just 'normal' evolution of the system. The magnitude of the calculated correction is relatively small (few nanometers) and they are also affected by the noise and fluctuations.

Your assignment

During your internship, you will work as a part of the Metrology and Machine Control Development and Engineering team. Your tasks include:

  • Investigating the possibility to implement different time filters;
  • Taking into account the time-series of the 'stability constants';
  • Minimizing noise in the control loop and improving its stability;
  • Optimizing the resulting performance of the Drift Control loop.

This is a master apprentice or graduation internship, with a duration of 3 to 6 months, for 2 to 4 days a week, starting in April 2022.

Your profile

To be the perfect match for this internship, you:

  • Are a master student in Physics, Mechanical Engineering, Applied Mathematics or similar;
  • Have a background in Chaos Theory or Control Theory;
  • Are familiar with MATLAB;
  • Have an affinity with Phyics Modeling and/or Control Theory;
  • Speak and write English on a sufficient level.

Please note that we can only consider students who are enrolled at a school for the entire duration of the internship.

Other information

Change the world – one nanometer at a time
Become an intern at a Dutch company that’s a global industry leader. You’ll gain valuable experience in a highly innovative environment – one that sparks your imagination and creativity. In addition to a monthly internship allowance of maximum €600 (plus a possible housing and/or travel allowance), you’ll get practical guidance from experts in the field and the chance to work in and experience a dynamic team environment.

ASML: be part of progress
ASML is a high-tech company headquartered in the Netherlands. We manufacture the complex lithography machines that chipmakers use to produce integrated circuits, or computer chips. What we do is at the heart of all the electronic devices that keep us informed, entertained and connected. Every day, you use electronics that simply wouldn’t exist without our machines.

Behind ASML’s innovations are engineers who think ahead. The people who work at our company include some of the most creative minds in physics, electrical engineering, mathematics, chemistry, mechatronics, optics, mechanical engineering, and computer science and software engineering.

We believe we can always do better. We believe the winning idea can come from anyone. We love what we do – not because it’s easy, but because it’s hard.

Students: getting ready for real-world R&D
We’re a global team of about 29,000 people of 120 different nationalities and counting. Headquartered in Europe’s top tech hub, the Brainport Eindhoven region in the Netherlands, our operations are spread across Europe, Asia and the US.

In such an environment, your colleagues may be sitting next door, or they could be thousands of kilometers away in a different country – or even working for a different company.

An internship at ASML is the opportunity to get to know not only the world of industrial-strength R&D, but yourself – you’ll discover just what excites you most. Will you design a part of the machine, or make sure it gets built to the tightest possible specifications? Will you write software that drives the system to its best performance, or work side-by-side with the engineers of our customers in a fab, optimizing a system to the requirements of the customer?

How will you be part of progress?
