Physics | Optical Engineering internship: optical column optimization

Location: Veldhoven, Netherlands

Introduction

The Optical Column department in Veldhoven develops advanced optical metrology systems that support chip manufacturing. In this internship, you will investigate opportunities to further improve optical metrology performance and reduce performance differences between systems. Depending on the assignment, your work may focus on hardware-related improvements within an optical column or on system-level investigations that leverage advanced measurement and data analysis capabilities.

Reducing system-to-system variations helps customers achieve tighter process control and improves the value of ASML's metrology solutions in a highly competitive market. You will work closely with experienced engineers and contribute directly to the understanding and optimization of optical system performance. This Physics | Optical Engineering internship offers a unique opportunity to combine experimentation, data analysis, and engineering insights in a cutting-edge technological environment.

Your assignment

During this internship, you will help evaluate how changes in optical subsystems, system configurations, or operational approaches influence metrology performance. Depending on the specific assignment, you may work directly with optical hardware and measurements in a laboratory or cleanroom environment, or focus on system-level investigations using remotely accessible setups, data analysis, simulations, and performance modeling.

Your work will contribute to improving consistency between systems and identifying opportunities for future design improvements. Your main responsibilities may include:

Support the evaluation of optical column or system-level modifications and their impact on metrology performance.

Perform measurements using experimental setups, laboratory equipment, or remotely accessible systems.

Collect, process, and analyze image and measurement data from metrology applications.

Develop and test hypotheses using experiments, simulations, or statistical methods.

Investigate performance variations and identify key influencing factors.

Visualize results and communicate findings through clear reports and presentations.

Recommend practical improvements based on evidence and identified trade-offs.

Collaborate with engineering experts to validate results and refine research questions.

This is a bachelor/master thesis internship for a minimum of 4 months, minimum 4 days per week (3 days on-site). The start date of this internship is as of February 2027.
