Abstract:
A semiconductor device includes an integrated circuit attached to a chip carrier in a flip chip configuration. A substrate extends to a back surface of the integrated circuit, and an interconnect region extends to a front surface of the integrated circuit. A substrate bond pad is disposed at the front surface, and is electrically coupled through the interconnect region to the semiconductor material. The chip carrier includes a substrate lead at a front surface of the chip carrier. The substrate lead is electrically coupled to the substrate bond pad. An electrically conductive compression sheet is disposed on the back surface of the integrated circuit, with lower compression tips making electrical contact with the semiconductor material in the substrate. The electrically conductive compression sheet is electrically coupled to the substrate lead of the chip carrier by a back surface shunt disposed outside of the integrated circuit.
