Are you a bachelor or master student in phsics or optics? Are you pro-active, communicative and enjoy challenges? Then this internship might be interesting for you!

Background information

With the SF15 (Laser light generation and transport) cluster we are responsible for generating a laser pulse and transporting it to the source vessel where EUV is generated. Once the beam is delivered inside the vessel it needs to meet certain conditions/specification to secure that good EUV can be generated. Being able to accurately model how the laser beam propagates through the transport system and eventually focuses on droplet is critical to drive future development and validate our system.

A detailed thermal-ABCD (with gaussian optics) exists which predicts beam behaviour throughout the beam transport system reasonably accurately. However it only has limited beam predictive capability as it is limited to 2D. The assignment will focus on improving the ABCD model from 2D to 3D enabling enanched modeling of the beam path and beam properties inside the vessel. Additionally the updated model will need to be validated against actual system data to secure accuracy

Your assignment

As an intern of the team, your tasks include:

  • Updating the model; updated on the shared location such that others can use it;
  • Writing a description of updated model, including a knowledge transfer document to be able to inform others how the updated models works and how to interface with the model;
  • Validating the model against actual system data.

This internship is intended to last for 3 to 6 months, 4 to 5 days per week, starting in September 2022.

Your profile

To be the perfect match for this internship, you:

  • Are a bachelor or master student in physics or optics;
  • Have knowledge of Matlab as well as Gaussian and geometrical optics;
  • Are pro-active, communicative, work well independently and enjoy challenges;
  • Speak and write English on an advanced level.

Please note that we may only consider interns who remain enrolled as students at their educational institute for the whole 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 28,000 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?
