Patent ID: 8359927

Claim:
A packaged differential pressure sensor, comprising: an exposed die flag in which a first vent hole is formed; a differential pressure sensor transducer die comprising a sensor diaphragm located between a backside and topside of the differential pressure sensor transducer die and sensor circuitry located on the topside of the differential pressure sensor transducer die, where the backside of the differential pressure sensor transducer is affixed to the exposed die flag so that a backside of the sensor diaphragm is directly vented to the environment through the first vent hole in the exposed die flag; a cap structure in which a second vent hole is located, where the cap structure is attached to the topside of the differential pressure sensor transducer die and so that the topside of the sensor diaphragm is vented to the environment through the second vent hole in the cap structure; one or more electrical connectors that are electrically coupled to the sensor circuitry located on the topside of the differential pressure sensor transducer die; and a molded body formed at least partially around the electrical connectors and around the differential pressure sensor transducer die without covering the first vent hole in the exposed die flag or the second vent hole in the cap structure, where the molded body covers the sensor circuitry located on the topside of the differential pressure sensor transducer die.
