Proceedings of International Solid State Sensors and Actuators Conference (Transducers '97).
In this paper, we present recent work on the fabrication and testing of a silicon bulk micromachined vacuum sensor. The fabrication process, electronics, and various modes of operation are described. The pressure sensitivity is demonstrated between 1
