Abstract

Control of the cavity pressure of packaged micro mechanical devices is important to achieve wide frequency range by critical damping. We developed a novel method using non-evaporable getters (NEG) and inert gas to control the cavity pressure in anodically bonded glass-silicon structure. From the pressure control experiments using silicon diaphragms, it was confirmed that the cavity pressure could be controlled as designed, that is, 1 and 100Torr. In application to an accelerometer, cavity pressure was successfully controlled for wide frequency response.
