Sensor assembly is one of the key technologies to improve the cost performance of silicon sensors. As a technology to achieve this aim, polysilicon sacrificial layer etching technology is presented. As its applications, a microdiaphragm pressure sensor with a reference pressure chamber and an integrated pyroelectric infrared sensor with a thermal isolated structure are also presented. Fabrication of a micro optical chopper is shown, and the future style of sensor devices is proposed.<
