Patent ID: 7718471

Claim:
A method of making a semiconductor package, comprising: providing a substrate having a plurality of contact pads formed over a first surface of the substrate; mounting a first semiconductor die to the substrate, the first semiconductor die having center-row contact pads; forming first wire bonds between each of the center-row contact pads of the first semiconductor die and the plurality of contact pads formed over the first surface of the substrate, the first wire bonds including an electrically insulative coating formed over the shaft of the first wire bonds, and the electrically insulative coating covering a portion of a surface of a bumped end of the first wire bonds; depositing an epoxy material over the first semiconductor die and around a portion of the first wire bonds; mounting a second semiconductor die to the epoxy material, the second semiconductor die having center-row contact pads; forming second wire bonds between each of the center-row contact pads of the second semiconductor die and the plurality of contact pads formed over the first surface of the substrate, the second wire bonds including an electrically insulative coating formed over the shaft of the second wire bonds, and the electrically insulative coating covering a portion of a surface of a bumped end of the second wire bonds; and forming an interconnect structure on a second surface of the substrate opposite the first surface.
