The Level Sensor is a light-based sensor. A promising route to decrease the measurement error by further improving the properties such as the colors, angles and polarization of the light. Your assignment tasks include, but is not limited to: Exploring how to optimize the Level Sensor properties, Simulation and modeling is part of the work, Determine wafer height map with 1nm accuracy, You will be a fully integrated member of the project team, join us in the office and be the owner of your own topic.
