Wafer stage, as an important module of ASML’s lithography machine, plays a crucial role in achieving high-acceleration motion and nano-meter performance. To mitigate the stage-induced vibration, an effective balance mass system has been commonly used. For the next generation wafer stage, new motion characteristics will be introduced, meaning the balance mass needs to be redesigned accordingly. In this assignment, we are aiming to design a new balance mass system for the new wafer stage, and to build a (simplified) dynamical model for analyzing system dynamics behavior. The new modular design would enable better system dynamics for improved performance, under a few challenging boundary conditions on volume, cost of goods, and stability
Your assignment- investigate existing (mechanical) design & requirements, and literature study on state of the art;
- make conceptual design for a new balance mass system, and evaluate aspects including but not limited to
manufacturability, mechanical behavior and stability, costs;
- create models for dynamics analysis and design optimization;
- create detailed designs and mitigate risks/impacts.
- document relevant findings and conclusions.
