Abstract:
1. A pressure sensor device, comprising: a carrier having a first surface and a second surface, wherein the first surface comprises a die attach area and a plurality of bond pads and the second surface comprises a plurality of electrically conductive bumps integral with the carrier, wherein a through hole is located within the die attach area; a piezo resistive transducer (PRT) semiconductor die having an active side attached to the carrier at the die attach area and electrically coupled to the bond pads of the carrier, wherein at least a part of the active side of the PRT semiconductor die is exposed in the through hole; a gel material deposited within the through hole and covering the at least a part of the active side of the PRT semiconductor die; and a mold compound covering the PRT semiconductor die and the bond pads.
