摘要

This paper describes the design and microfabrication of MEMS 2D microgyroscope. The MEMS 2D microgyroscope is a resonating type of gyroscope. The primary mode is driven by electrostatic rotary comb drive. The oscillations of the secondary modes are sensed by differential capacitances detection between the circular proof mass and substrate electrodes. The microfabrication of the 2D microgyroscope combines glass cavity etching, anodic boding of glass and SOI wafer as well as DRIE of device layer of SOI wafer. The MEMS 2D microgyroscope can be widely applied in navigation systems, IMU, automobiles and high-end consumer electronics.
