Semiconductor sensor assembly for harsh media application
A semiconductor sensor assembly for use in a corrosive environment comprises a processing device comprising at least one first bondpad of a material which may be corroded by a corrosive component in a corrosive environment; a sensor device comprising at least one second bondpad consisting of and/or being covered by a first corrosion resistant material; at least one bonding wire for making a signal connection between the at least one first bondpad of the processing device and the second bondpad of the sensor device. The processing device is partially overmoulded by a second corrosion resistant material, and is partially exposed to a cavity in the corrosion resistant material, with the sensor device being present in the cavity. A redistribution layer is provided to enable signal connection between the processing device and the sensor device is physically made in the cavity while the second corrosion resistant material covers the first bondpad.
