EE C245/ME C218: Introduction to MEMS Design
EE C245/ME C218: Introduction to MEMS Design (Fall 2012, UC Berkeley). Instructor: Professor Clark Tu-Cuong Nguyen. This course provides an introduction to physics, fabrication, and design of micro-electromechanical systems (MEMS).
Micro and nanofabrication processes, including silicon surface and bulk micromachining and non-silicon micromachining. Integration strategies and assembly processes. Microsensor and microactuator devices: electrostatic, piezoresistive,
piezoelectric, thermal, magnetic transduction. Electronic position-sensing circuits and electrical and mechanical noise. CAD for MEMS.
