Are you a master student in Physics or Engineering with an affinity for hardware design and simulations? Then this internship could be interesting for you!

Background information

At ASML Delft, we are developing a multi-beam electron microscope for in-line wafer inspection. The microscope uses an array of e-beam apertures to control the beams. The cathode and the apertures require, for different reasons, ultra high vacuum. Given the novel design of the microscope, the vacuum design is not optimized nor tested.

Your assignment

The purpose of this intership is to study relevant vacuum designs with the help of both analytical and Monte Carlo simulation tools. Establishing a good workflow for the calculations, based on available 3D modeling and simulation tools is also a goal of the intership. To give an idea, the following activities may be part of the intership: study a toy-model (i.e. simplified) vacuum systems to compare analytical and Monte Carlo methods, calculate / optimize current vacuum design, analyze vacuum performance of available research setups, describe a workflow that would facilitate the next vacuum designs.

Your profile

To be the perfect match for this internship, you:

  • are a master student in (applied) Physics or in a relevant engineering discipline;
  • have an affinity with hardware design, physics modelling and simulations;
  • have good communication skills in English and you enjoy explaining technical problems.

This is a master apprentice internship, with a minimum duration of 6 months, 5 days per week, starting as soon as possible.

Please note that we may only consider applicants who are enrolled as a student to a university for the whole duration of the internship.

This position requires access to U.S. controlled technology, as defined in the United States Export Administration Regulations. Qualified candidates must be legally authorized to access such U.S. controlled technology prior to beginning work. Business demands may require ASML to proceed with applicants who are immediately eligible to access U.S. controlled technology.

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?
