Optics Graduation Internship: Level sensor process dependency

Optical engineering



In a nutshell


Veldhoven, Netherlands


No experience (Student)



Job Category

Optical engineering, Physics, Mathematics


Are you a graduate student with a background in Optics? Then this assignment could be interesting for you.

Job Mission

The Level Sensor is an optical sensor at the heart of any ASML scanner. It measures the height profile of the wafer. To ensure the best possible performance it is needed to take into account the complicated optical interaction of the Level Sensor light with every possible wafer surface. The effect of this interaction on the Level Sensor is known as ‘process dependency’. Process dependency is the main driving force for Level Sensor development.

Job Description

Process dependency is qualified on each machine, using a set of specially designed wafers. You will investigate the effect of these wafers on the results of the qualification test, and propose improvements.

For this you need to dive deep into the optical model behind the test method. You will analyze test results (using Matlab), and, if the planning permits, you will prepare and execute tests yourself on an ASML scanner in the cleanroom.

You will work in an interdisciplinary team within D&E, involved in both Level Sensor hardware and software development. Also you will interact with suppliers.


You are a Master’s student in physics, optics, mathematics, or a related discipline. You have strong analytical skills and an affinity for optics and you can work autonomously. Additionally, you have at least a basic knowledge of Matlab.

This is a graduation assignment for 3-5 days a week with duration of minimum 4 months. the start date is as soon as possible.

Please keep in mind that we can only consider students (who are enrolled at a school during the whole internship period) for our internships and graduation assignments.

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 of 500 euro (maximum), plus a possible housing or travel allowance. In addition, you’ll 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 software 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.

Students: Getting ready for real-world R&D
Pushing technology further is teamwork, and our R&D team is more than 5,500 people strong, with major sites on three continents. Dozens of diverse, interdisciplinary teams work in parallel to meet a challenging development schedule.

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 your opportunity to get to know this world of industrial-strength R&D and get a feel for that 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?
