Abstract:
This paper presents a novel anchoring für polysilicon-based movable microstructures which significantly improves the mechanical resilience of MEMS. The concept is modelled using FEM simulation and experimentally validated. Test devices containing movable microstructures realized with the novel anchoring withstand 3 times higher mechanical loads compared to identical test devices with an anchoring corresponding to the state of the art.
