Microelectromechanical System Technology and Its Application

Microelectromechanical system (MEMS) technology makes it possible the moralization and integration of the products based on the material of silicon. This technology is divided into four categories: body, surface, metal and compound micromechanical processes. The basic technologies included in the micromechanical system are erosion, si-bond, multiplayer film sediment without stress, sacrifice layer, LIGA and the combined technologies based on them. The applications of micro-sensors, micro-machines, mechanism filter and resonant filters are presented, and the further development of technology is discussed.
