Patent ID: 8341828

Claim:
An apparatus for incorporating a thin foil into a semiconductor package, comprising: a carrier having a multiplicity of cavities; a metallic foil overlying the carrier, the foil having a top side and a bottom side, the bottom side of the foil being in direct contact with the carrier, the foil having a shape that bends to follow contours of the cavities and the carrier, the metallic foil being in direct contact with and overlying sides and bottoms of the cavities in the carrier; a plurality of integrated circuit dice, each die having an active surface and an opposing back surface, the back surface of each die being attached to the top side of the foil; and a plurality of bonding wires that electrically connect the active surface of each integrated circuit die to the top side of the foil; and a molding material that encapsulates the dice and bonding wires, wherein the molding material extends into and fills the cavities in the carrier, the metallic foil being sandwiched between the molding material and the carrier.
