Abstract:
A package for packaging an Integrated Circuit die in a cavity provided in a heat sink, comprising:an Integrated Circuit die having a ground point, the Integrated Circuit die being a flip chip device; a substrate comprising: (i) three layers; and (ii) an opening there-through for establishment of a ground connection between the Integrated Circuit die and a heat sink; a heat sink, the heat sink having a cavity having a bottom surface and sidewalls; a first adhesive layer over the bottom surface of the cavity for attaching the IC die to the heat sink; the IC die attached to the heat sink by positioning the IC die over the first adhesive layer; a plurality of wire bond connections between the IC die and the substrate; a conductive material through the opening provided through the substrate; a wire bond connection between the ground point of said IC die and the conductive material provided through the opening through the substrate; an encapsulation layer within and adjacent to the cavity for attaching the IC die to the heat sink; and a plurality of attached solder balls.
