Abstract
A pressure transducer assembly configured for low-pressure measurements in water or high humidity environments, the pressure transducer assembly having a non-corrosive housing, an upside-down mounted pressure sensor chip comprising silicon and contact glass, and an electrically insulating and stress-absorbing spacer layer disposed between the non-corrosive housing and the contact glass of the sensor chip, the spacer layer is matched to a coefficient of thermal expansion (CTE) of one or more of the glass and the silicon of the sensor chip to absorb stress and improve reliability. The pressure transducer assembly may be suitable for use in microphone and/or hydrophone applications.
