Patent ID: 8297125

Claim:
A differential pressure sensor, comprising: a pressure sensor die having a pressure sensor with a sensing diaphragm, the pressure sensor die further having a first side and a second side with a plurality of die bond pads formed on the first side of the pressure sensor die; a cap including a top and adapted to cover said pressure sensor and isolate said pressure sensor from said die bond pads, said cap having an opening formed in the top, wherein a measured media can pass through the opening in said cap and reach said diaphragm of said pressure sensor while the cap isolates the bond pads from the measured media; and a first port at least partially coupled to said cap, and a second port at least partially coupled to the second side of said pressure sensor die, wherein said first port and second port are configured to allow the measured media to contact said first side and said second side, respectively, of said diaphragm of said pressure sensor.
