# Physics | Engineering internship: Multi-beam SEM performance optimization

Introduction At ASML Delft, we are developing a next-generation multi-beam scanning electron microscope (SEM) for semiconductor wafer inspection. This internship focuses on improving the imaging performance of advanced inspection systems used in semiconductor manufacturing. Due to the microscope's large field of view and shallow depth of focus, wafer surface variations can affect image quality and inspection efficiency. During this internship, you will help develop methods to better understand these effects and improve system performance. This internship offers the opportunity to combine physics, data analysis, and engineering in a highly innovative environment. Your assignment As an intern, you will contribute to the optimization of multi-beam SEM performance through calibration measurements, data analysis, and performance evaluation. You will work closely with specialists from different engineering disciplines to gain insight into electron-optical system behavior and identify opportunities for improvement. Your work will support the development of more robust inspection strategies and improved imaging performance. Your main responsibilities will be: Design and execute calibration
