CAPACITIVE PRESSURE SENSORS FOR HIGH TEMPERATURE APPLICATIONS

A capacitive pressure sensor includes a substrate wafer and a diaphragm wafer. The substrate wafer defines a substrate recess with a first recess. The diaphragm wafer defines a diaphragm recess with a second recess. The diaphragm wafer is bonded to the substrate wafer such that the substrate and dia...

Zusammenfassung:	A capacitive pressure sensor includes a substrate wafer and a diaphragm wafer. The substrate wafer defines a substrate recess with a first recess. The diaphragm wafer defines a diaphragm recess with a second recess. The diaphragm wafer is bonded to the substrate wafer such that the substrate and diaphragm recesses form a height differentiated pressure chamber.
