Patent ID: 7952153

Claim:
A differential pressure sensing device package, comprising: a carrier, having a upper surface, a lower surface, and a through-hole; at least one differential pressure sensing device, bonded and electrically coupled with the upper surface of the carrier, having an active surface with a active region and at least one bonding pad and a back surface with a recess corresponding to the through-hole of the carrier and being in communication with an external environment; and a molding compound, encapsulating the upper surface of the carrier, the differential pressure sensing device, and a bonding pad area of the differential pressure sensing device; the molding compound having an opening above the active region of the differential pressure sensing device to expose the active region of the differential pressure sensing device and make the active region be in communication with the external environment, wherein the opening is defined and surrounded by an innermost sidewall of the molding compound, and the innermost sidewall of the molding compound extends directly from the active surface of the differential pressure sensing device.
