Patent ID: 7919853

Claim:
A semiconductor package, comprising: a substrate having an insulative layer having a first surface and a second surface, an aperture formed through the insulative layer of the substrate, conductive patterns formed on the first surface and the second surface of the insulative layer; a semiconductor die having a first surface and a second surface positioned in the aperture of the insulative layer of the substrate, the semiconductor device electrically coupled to the conductive patterns formed on the first surface of the insulative layer; a heat spreader having a first surface and a second surface, the second surface of the semiconductor die attached to a first surface of the heat spreader by a first adhesive, wherein the heat spreader spans the aperture and is peripherally attached to the second surface of the substrate by a second adhesive; at least one solder contact formed on a second surface of the heat spreader to emit heat from the heat spreader to an external device; an encapsulant encapsulates the aperture, the semiconductor die, and the electrically conductive wire; and an opening formed between the first adhesive and the second adhesive and between an exposed portion of the encapsulant and the heat spreader.
