Patent ID: 7900521

Claim:
A packaged pressure sensor, comprising: an exposed die flag in which a vent hole is formed; a pressure sensor transducer die comprising a sensor diaphragm formed on a backside of the pressure sensor transducer die and sensor circuitry formed on a topside of the pressure sensor transducer die, where the backside of the pressure sensor transducer is affixed to the exposed die flag so that the sensor diaphragm is directly vented to the environment through the vent hole in the exposed die flag; one or more electrical connectors that are electrically coupled to the sensor circuitry formed on the topside of the pressure sensor transducer die; and a molded body formed at least partially around the electrical connectors and around the pressure sensor transducer die without covering the exposed die flag, where the molded body protects the sensor circuitry formed on the topside of the pressure sensor transducer die from corrosive external environmental conditions.
