Patent ID: 7196415

Claim:
An integrated circuit (IC) package, comprising: a substantially planar substrate having a plurality of contact pads on a first surface electrically connected through said substrate to a plurality of solder ball pads on a second surface of said substrate; an IC die having a first surface mounted to said first surface of said substrate, wherein said IC die has a plurality of I/O pads electrically connected to said plurality of contact pads on said first surface of said substrate; and a heat sink assembly coupled to a second surface of said IC die and to a first contact pad on said first surface of said substrate to provide a thermal path from said IC die to said first surface of the substrate; wherein the heat sink assembly includes: a first heat sink element that has a first surface and a second surface, wherein said first surface of said first heat sink element is attached to said second surface of said IC die, and wherein said second surface of said first heat sink includes at least one bond pad; and a second heat sink element coupled to said second surface of said first heat sink element and to said first contact pad.
