For fast and accurate force measurements, e.g., sampling the impact of a liquid droplet, a highly sensitive high-bandwidth force sensor is required. High-sensitivity and high-bandwidth are contradictive specifications in recently published force sens

Micro-electro-mechanical-systems (MEMS) structures with different in-plane dimensions often need to be released simultaneously from the bulk of the wafer and a single dry etching or wet etching technique cannot fulfill all release requirements. In th
