Abstract:
1. A semiconductor ball grid array package, comprising: a ball grid array packaging substrate; a semiconductor die mounted on and electrically connected with the substrate, the die having a top surface opposite a bottom surface, the bottom surface being used to mount the die to the substrate; a heat sink connected with the substrate and at least partially surrounding the die without contacting the die; and a mold compound encapsulating the die on the substrate and contacting the heat sink such that a first portion of the heat sink is exposed outside the mold compound and a second portion of the heat sink is within the mold compound, the mold compound being between the heat sink and the die, the mold compound comprising a mixture of an epoxy resin and ceramic filler material that increases thermal conductivity of the mold compound, and provides the principal thermal connection between the die and the heat sink.
