Internship: Reconstruction of measured electrostatic voltage data


Electrical engineering


In a nutshell


Veldhoven, Netherlands


No experience (Student)



Job Category

Mathematics, Electrical engineering, Physics


Are you a Master student with a background in Mathematics or Electronics? Do you have the willingness to perform measurements to obtain input for your algorithm? Then this assignment is interesting for you.

Job Mission

Electrostatic clamps are used in EUV systems to hold the wafer. Sometimes the top surface of such electrostatic clamp can become charged. This remaining charge has a negative influence on our system performance. To measure the residual charge distribution on the top surface of such a clamp, the clamp surface is scanned with an electrostatic voltmeter (ESVM). This gives an image of the potential distribution on the clamp surface. This “potential distribution image” is blurry due to the limited resolution of the ESVM sensor. Small details become vague and makes interpretation of the results difficult.

Job Description

In several other domains (microscopy and astronomy) image processing is used to enhance blurred images. Goal is to find a suitable technique for enhancing the ESVM images. Part of the work will consists of measuring reference images and measuring the sensor transfer function. The other part of the assignment will consist of making and implementing an image reconstruction algorithm in MATLAB that can be used on the measured data. Finally the image reconstruction algorithm should be tested on some existing images. In the ideal case some guidelines should be drawn up to give a relation between measurement parameters and image resolution.


You are a Master student in Mathematics or Electrical Engineering. You have in depth knowledge of MATLAB and you have affinity with image processing and electrostatics. You have the willingness to perform measurements to obtain input for your algorithm. It is expected to show self-dependency and you are a quick learner. The English language is required, both written and verbally.

This is a Master graduation or apprentice internship for minimum 4 months. The number of days depends on the duration of the internship, with a minimum of 3 days a week. The start date is as of September 2020.

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?
