Are you a bachelor or master student in mechanical engineering? Are you interested in temperature dependent strength and stiffness calculations? Do you have an affinity on how to test the critical parameters in their design to validate performance? If so, this internship could be interesting for you!

Background information

The recent electronics shortage gave a strong push towards higher output of lithography systems. To enable higher throughput, higher EUV source powers are required. One bottleneck for higher source power is the feed pressure of the liquid tin supply.
The liquid tin is used to create a constant stream of droplets to be hit by a high power laser, which creates a hot plasma that radiates the EUV light. Higher pressure gives more droplets, which gives more EUV light.
The current system is pressurized by means of gas. There are several technical limits to this system which will be reached in the coming years. To enable higher pressures (>2000 bar) a new pressurization method is envisioned using the expansion of the tin solid-liquid phase change. By melting a fluid in a confined space tremendous pressures can be reached. This internship focusses on finding a way to harness this pressure in a practical way.

Your assignment

With the aid of experienced designers you will:

  • Define a test setup to validate the concept of a phase-change powered tin pump. You need to prove by analysis that the setup can withstand both the temperatures (250 C) and pressures (>2000 bar);
  • Design a high pressure pump;
  • Prove that the design can withstand the desired pressures;
  • Come up with a validation test plan;
  • Oversee the integration of the design in a test setup;
  • Test and validate your design.

You’ll be working in close collaboration with experienced architect(s) and experts to develop enabling technology for the next generation lithography tools.

Your profile

To be the perfect match for this internship, you:

  • are a bachelor, HBO student looking to do your graduation project or a master student looking to gain work experience;
  • have a background in Mechanical Engineering;
  • have experience in designing, material knowledge;
  • have an affinity with how manufacturing works;
  • have a practical approach and is capable of dealing with changing requirements and new insights in the design;
  • like to work in a multidisciplinary team;
  • speak and write English proficiently.

The preferred start date is as soon as possible, with a minimum duration of 6 months.

Please note that we may only consider students who remain enrolled at their educational facility 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?
