# Physics | Engineering internship: electron optical sensitivity simulations

Introduction At ASML’s Delft office, you will join a team developing a multi-beam electron microscope used to inspect semiconductor wafers during production. A key part of this system is a micro-electromechanical (MEMS) module that shapes and directs electron beams. Small manufacturing variations in this module can influence electron optics performance, including beam focus and alignment. Understanding these effects is essential for designing reliable and robust products. During the internship, you will help generate insights that support future technology development and improve system performance. Your assignment During the internship, you will work closely with experienced engineers and researchers to investigate the impact of manufacturing tolerances on a MEMS module used in advanced electron microscopy. You will use simulations and data analysis to understand how geometrical imperfections affect electron beam behavior and identify the most critical design sensitivities. Your findings will support design decisions and contribute to the development of next-generation inspection technology. Your main responsibilities will be: Adapt and parameterize existing simulation models to r
