Introduction
ASML focuses on developing innovative solutions to maximize the production of extreme ultraviolet (EUV) light by harnessing high-power source lasers. The primary goal of this internship is to investigate the leakage mechanism of EOM (Electro-Optical Modulator). To achieve this, you will perform tests on different EOM parameters such as incident angle, input polarization, high-voltage setting, etc. and measure the resulting transmission and leakage through an EOM. The final objective is to establish a clear understanding of the EOM performance. This project offers a valuable and hands-on learning experience for an intern.
Your Assignment
Your main tasks will include:
Familiarize yourself with the work done on EOM leakage mechanism in ASML;
Read up on literature on the EOM leakage mechanism;
Help in building the set up and then perform EOM measurements;
Analyze the effect of each parameters on the leakage and determine the relation between the parameters and the leakage behavior;
Analyze the measurements and possibly propose a design or improvements;
This is a Master internship for 8 to 12 months, working 5 days per week. This internship is also suitable for writing a thesis. The start date for this internship is September 2026 and is flexible.
Your Profile
To be a fit for this assignment, you:
Are studying a master's in Physics, Optics or relevant;
Are proactive and self-propelling;
Possess data analysis and problem-solving skills;
Have some hands-on experience in an optics lab;
Preferable have some experience with numerical models;
Have good communication skills in English (verbal and written).
Other requirements you need to meet:
- You are enrolled at an educational institute for the entire duration of the internship, and you are at least 18 years old at the start of the internship;
- If you are a non-EU citizen, studying in the Netherlands, your university is willing to sign the documents relevant for doing an internship (i.e., Nuffic agreement);
- You attach your cover letter with a clear motivation on why you are interested in this internship assignment in particular;
- You need to be located in the Netherlands to be perform your internship. In case you are currently living/studying outside of the Netherlands, your application shows the willingness to relocate.
