Claim Text:
1. A semiconductor sensor device, comprising: a device substrate; a micro controller unit (MCU) die attached to the device substrate; a pressure sensor package having a sensor substrate and a pressure sensor die electrically connected to the sensor substrate, the sensor substrate having a front side with the pressure sensor die attached thereto, a back side, and an opening from the front side to the back side, wherein the pressure sensor die is flip-chip mounted to the sensor substrate using conductive bumps, and the sensor device further comprises a pressure-sensitive gel covering the conductive bumps and the pressure sensor die, and at least partially filling the opening in the sensor substrate; and a molding compound encapsulating the MCU die, the device substrate, and the pressure sensor package, the molding compound having an outer surface; wherein the back side of the sensor substrate and the opening in the sensor substrate are exposed on the outer surface of the molding compound.
