Are you a Master student in Chemistry, Physics or Material Science? Are you an experimentalist who has a hands-on mentality? Then this assignment could be interesting for you!

Job Mission

EUV optics is the heart of the ASML scanner. It consists of highly complex optics with multilayer mirrors reflecting and focusing extreme ultraviolet light. These mirrors have to operate in extremely aggressive environment of high-energy radiation, reactive plasma and gas radicals and at high temperature for several years without degrading to ensure scanner productivity. Optics lifetime group aims to achieve optimal and reliable EUV system performance by predicting and securing EUV optics lifetime, through contamination control and prevention of optical degradation. Within the OLT group the HIO / Oxidation (HIO2) team works on optics lifetime models, mechanisms and mitigations for Hydrogen Induced Outgassing (HIO) and mirror oxidation.

Job Description

Current hydrogen induced outgassing contamination models for optics are based on sum of individual contaminants where interaction between contaminants is neglected. The main goal of the project is to investigate how different contaminants and contaminant levels, individually and when combined, influence the matrix composition under hydrogen plasma environment conditions in test setups. You will work closely with engineers within the team to define a test-plan on HIO as input for optics lifetime models. You will execute the tests and perform material analysis at an external lab and report the results. Tests will be performed in cooperation with the Plasma-Material Interaction (PMI) team, who is responsible for the test equipment. This project allows for combined hands-on work with planning, analyzing and reporting and you will have the opportunity to present your results to your colleagues from different teams.


You are a Master student in Chemistry, Physics, Material Science or a related discipline.

  • You are an experimentalist who has a hands-on mentality.
  • You are proactive, who is capable of working accurately and maintaining overviews in a dynamic environment.
  • Furthermore, the English language is required, both written and verbally.

This is an Master apprentice or master graduation internship for 4 to 5 days a week with duration of 5-8months. 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?
