Physics Graduation Internship: High Power Energy Sensor


Optical engineering

In a nutshell


Veldhoven, Netherlands


No experience (Student)



Job Category

Physics, Optical engineering


Are you a Master student in Experimental Physics with a strong background in Mathematical Simulation and Data Analysis? Are you looking for a graduation project after summer? Then this assignment could be interesting for you!

Internship type: Graduation (thesis)

Start date: After summer

Background Information

This assignment takes place in the DUV Development & Engineering Illumination, Sources and Dose Control group.
In the scanner a so-called “Energy Sensor” (ES) measures the energy of DUV laser pulses entering the scanner on a pulse-to-pulse basis. This is used to control the overall light dose during exposure of the wafers. For future generations of scanners we will increase the power of the light and we need to know if the current design is capable of handling these higher powers and if not, what improvements are needed.

Your Assignment

You will investigate experimentally and theoretically the power handling capabilities of the ES. This will involve on-scanner experiments where you will look at the linearity of the ES at higher powers. You will also do thermal modeling and simulation of the current ES. If you find that the current sensor is not capable of handling the higher power, you will make recommendations how to improve its design.

Your Profile

• You are a Master graduation student in Experimental Physics
• You have a strong background in Mathematical Simulation and Data Analysis.
• Experience with optics, lasers, optical sensors is highly preferred.
• You should be able to function in a multidisciplinary environment and discuss your tests and results not just with other physicists but also with people from disciplines such as software, electronics and mechanical development.

This is a Master graduation internship for 5 days a week with a duration of minimum 6 months. The start date is as of September 2021.

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?
