Abstract

A pressure sensor device which uses appropriate passivation materials/patterns to make the device more robust and resistant to a hot and humid environment. The pressure sensor device uses moisture resistant passivation material(s) covering exposed glass areas, including sidewalls, and bonding interfaces to avoid the glass and bonding interfaces absorbing and reacting with moisture, thus maintaining the integrity of the device output after exposure in a humid/hot environment. These passivation materials/patterns used for the MEMS devices described may be applied to any MEMS based sensors and actuators using glass as one type of material for fabrication. The pressure sensor devices may be front side absolute pressure sensors, differential pressure sensors, or back side absolute pressure sensors.
