Patent ID: 8866268

Claim:
A semiconductor package structure, comprising: a semiconductor die; a thermally conductive film, the thermally conductive film disposed on the bottom of the semiconductor die; a substrate, the substrate substantially comprised of a conductive material or semiconductor material, a first hole formed on the substrate, the first hole passed through the substrate, and the semiconductor die disposed in the first hole; a plurality of conductive patterns, the conductive patterns disposed on the substrate, the conductive patterns not electrically connected to each other, and the conductive patterns not electrically connected to the substrate; and at least one insulator, the insulator connected between the semiconductor die and the substrate; wherein the semiconductor die is electrically connected to the conductive patterns, the thermally conductive film has a protruding center region disposed under a bottom portion of the semiconductor die and a plurality of bending up end corners, the semiconductor die is fixed by the insulator and the thermally conductive film, and the thickness of the insulator is controlled so as to support the semiconductor die.
