Abstract
A pressure sensor structure includes a sensor body including a diaphragm plate that functions as a sense electrode, a base electrode that faces the diaphragm plate, and a sidewall layer maintaining a gap between the diaphragm plate and the base electrode, and a conductive guard substrate to support the sensor body. The sidewall layer includes a guard electrode layer and upper and lower electrically insulating layers to electrically insulate the guard electrode layer. An electrically insulating layer is between the guard substrate and the sensor body to electrically insulate the guard substrate. The guard substrate is electrically connected to the guard electrode layer to function as a guard electrode together with the guard electrode layer.
