Abstract:
1. A method of assembling a die-down array integrated circuit (IC) device package, comprising: (a) coupling a first surface of a substrate to a first surface of a heat spreader, wherein said substrate has a central opening that is open at said first surface of said substrate and a second surface of said substrate, wherein said central opening overlaps a central cavity formed in said first surface of said heat spreader; (b) mounting a first surface of an IC die to said first surface of said heat spreader within said central cavity; (c) coupling a plurality of bond pads on a second surface of said IC die to corresponding bond pads on said second surface of said substrate with a plurality of wire bonds; and (d) coupling a first surface of an interposer to said second surface of said IC die, wherein a plurality of electrically conductive bumps on said second surface of said IC die are coupled to corresponding bond pads on said first surface of said interposer.
