Are you a final year Master student in Physics or Optics? Do you have knowledge of interferometry? Then this graduation assignment could be interesting for you!

Job Mission

Within the DUV Image Sensors Development & Engineering team we develop image sensors that are a key part of the lithography system that ASML produces and develops. In order to be able to use them we also help to develop masks or reticles that are used as source modules and which flatness play an important role in our sensors measurement accuracy and reproducibility.

Lately we have faced challenges on the flatness qualification of the mentioned reticles which are suspect of beingcreated during the manufacturing process at the supplier.

We would like to challenge an student that could check the shape dependence on design and manufacturing process.

Job Description

You will:
-Investigate manufacturing process of the reticle together with ASML and its supplierand identify the manufacturing step(s) in which the unflattens is introduced.
-Come up with solution(s) to avoid this defect in the reticle manufacturing process
-Roll out the solution in the Image Sensors Supplier of ASML and prove that reticle flatness is achieved


- You are a final year Master student in Optics, Physics or related.
- You have knowledge of interferometry.
- You are a flexible and committed team player with a pragmatic attitude, result orientation and an analytical view.
- You have excellent command of the English language.

This is a Master graduation internship for 5 days a week with a duration of a minimum 6 months. 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.
