Patent ID: 7235889

Claim:
A semiconductor integrated circuit (IC) package comprising: a packaging substrate suitable for mounting thereto an integrated circuit die wherein the substrate includes a die bonding pad and electrical bonding surfaces on first side of the substrate and solder balls on a second side of the substrate, said solder balls being electrically connected with at least some of the electrical bonding surfaces by electrically conductive vias that pass through the substrate; a heat spreader mounted on a first side of the substrate and configured to include a set of cutout openings to expose the electrical bonding surfaces so that they can be wire bonded to the die; an integrated circuit die mounted to the heat spreader such that the die is in thermal communication with the heat spreader and such that the heat spreader lies in between the die and the substrate thereby enabling a portion of the heat generated by the die to be dissipated from the die through the heat spreader and wherein the die is electrically connected to some of the solder balls using wire bonds to electrically connect with the electrical bonding surfaces; a protective mold cap for encapsulating the die, wire bonds, and at least a portion of the heat spreader; and wherein a portion of the heat spreader extends beyond the mold cap towards an edge portion of the substrate to expose an outer rim of the heat spreader.
