Are you a master student with a background in Physics or Mathematics? Do you have knowledge in Python and inverse problems? Are you eager to learn and able to work independently? Then this internship might be interesting for you!

Background information

ASML's Research Department leads research projects to address the gaps in today's engineering problems and explore future technologies to enable the future of the semiconductor industry.

Your assignment

The trend in miniaturization of devices leads to more and more complex 3D designs of transistors like Gate-all-around (GAA), Forksheet and CFET. Metrology needs for these types of devices are huge. However, their 3D-character makes forward simulations expensive, in particular if global sensitivity landscapes are studied, which are paramount in order to set up model based reconstruction.

Surrogate modeling is one way around these issues. Via the polynomial chaos approach, it is possible to generate a surrogate model based on only the forward model outputs. This model is fast to evaluate thanks to analytical differentiation and it has a built-in global sensitivity analysis via Sobol indices.

As an intern, you will explore this approach on a state of the art GAA in simulation using Python.

Your profile

To be the perfect match for this internship, you:

  • are a student with a background in Physics or Mathematics;
  • have knowledge in inverse problems, rigorous Maxwell solvers and Python;
  • have, preferably, knowledge in scatterometry.
  • have great communication skills in English, both verbally and written.

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

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 free public transport), 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?
