Patent ID: 7812442

Claim:
A high power ball grid array package comprising: a printed circuit board having a through hole at its center, the printed circuit board comprising a substrate, and connection pads on the substrate at one side of the printed circuit board; a matrix of solder balls disposed on the printed circuit board at the one side thereof, and surrounding the through hole and the connection pads of the printed circuit board; a heat spreader disposed on the other side of the printed circuit board; a semiconductor chip mounted to the heat spreader, and including a plurality of bonding pads; bonding wires bonding the bonding pads of the semiconductor chip to the connection pads; and a passive film filling the through hole at the center of the printed circuit board, wherein the heat spreader comprises: a chip supporting body to which the semiconductor chip is adhered; a ceramic film disposed on the chip supporting body; a first metal layer disposed on one surface of the ceramic film; a second metal layer disposed on the other surface of the ceramic film and interposed between the ceramic film and the printed circuit board, the second metal layer having a through hole, the chip supporting body being disposed within the through hole of the second metal layer so as to be surrounded by the second metal layer, the chip supporting body being mounted to the ceramic film, and wherein the semiconductor chip is electrically isolated from the metal layers of the heat spreader; and a protection layer disposed on the second metal layer and protecting the second metal layer.
