Mechanical Engineering | Applied Physics Internship: Thermal Contact Conductance Estimation Model

Mechanical engineering


In a nutshell


Veldhoven, Netherlands


No experience (Student)



Job Category

Mechanical engineering, Physics


Are you a master student in Mechanical Engineering or Applied Physics, who is graduating in a field related to Thermal Engineering? Are you interested in investigating the available experimental and simulation data on Thermal Contact Conductance? Then this internship could be interesting to you!

Background Information

The latest generation of lithography machines uses light in the extreme ultra violet range. Since light of this wavelength (13.5 nm) is absorbed by any optical medium, reflective optics in a vacuum are used. Small deviations in the positioning by the machines can cause significant errors in the performance. Thermal effects get increasingly more dominant in these errors, partially influenced by Thermal Contact Conductance. Since the next generation of lithography machines needs precision of submodules to be in the order of 10 picometer, even small thermal effects are relevant to design evaluation and need to be estimated to arrive at the desired performance.

Your Assignment

There is existing literature on Thermal Contact Conductance empirical models, and also some measurements have been done. However, there seems to be a mismatch between models and measurements, thereby reasoning the need for a broader application range. The intern is to come to an analytical or empirical model for estimating Thermal Contact Conductance between surfaces early in the machine design. You will:

  • Investigate the available experimental and simulation data, perform literature research
  • Analyze and compare to the results, try to match the results to a theoretical frame work or scaling law.
  • If needed, perform/arrange for additional measurements and/or simulations
  • Finalize a model, document and present it such that it can be applied for machine design.

You’ll be working in close collaboration with experienced engineers on answering questions currently blocking the design of the next generation lithography tools.

Your Profile

  • You are a master student in Mechanical Engineering or Applied Physics, who is graduating in a field related to Thermal Engineering.
  • You are looking to do your graduation project and you are available for 5 days a week with a minimum duration of 6 months.
  • You are autonomous and have good communication skills in English.
  • The start date is as soon as possible.

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

Other information

What ASML offers
Your internship will be in one of the leading Dutch corporations, gaining valuable experience in a highly dynamic environment. You will receive a monthly internship allowance based on your educational level and number of days per week, plus a possible housing or travel allowance. More information on the allowances can be found on our website. In addition you will get expert, practical guidance and the chance to work in and experience a dynamic, innovative team environment.

ASML: Be part of progress
We make machines that make chips – the hearts of the devices that keep us informed, entertained and safe; that improve our quality of life and help to tackle the world’s toughest problems.

We build some of the most amazing machines that you will ever see, and the applications to run them. Never satisfied, we measure our performance in units that begin with pico or nano.

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. At ASML we are always pushing technology further.

Students: Getting ready for the real-world
Teamwork is key within ASML. Our R&D team is more than 5,500 people strong and worldwide we form one big team with over 25,000 employees. These colleagues have 123 different nationalities and work at our major sites on three continents.

Dozens of diverse, interdisciplinary teams work in parallel to meet a challenging development schedule. In this inspiring 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 your opportunity to get to know this world and get a feel for that excites you most. Use your education, gain real-life working experience and explore the world of high-tech – all at the same time.

How will you be part of progress?
