Abstract:
The disclosed principles provide a stress buffer layer between an IC die and heat spreader used to dissipate heat from the die. The stress buffer layer comprises distributed pairs of conductive pads and a corresponding set of conductive posts formed on the conductive pads. In one embodiment, the stress buffer layer may comprise conductive pads laterally distributed over non-electrically conducting surfaces of an embedded IC die to thermally conduct heat from the IC die. In addition, such a stress buffer layer may comprise conductive posts laterally distributed and formed directly on each of the conductive pads. Each of the conductive posts thermally conduct heat from respective conductive pads. In addition, each conductive post may have a lateral width less than a lateral width of its corresponding conductive pad. A heat spreader is then formed over the conductive posts which thermally conducts heat from the conductive posts through the heat spreader.

Claim (Index 15):
An integrated circuit (IC) package, comprising:\n an IC die having electrically conducting bond pads and non-electrically conducting surfaces distributed on an exterior of the IC die; electrically conductive vias connected to one or more of the electrically conducting bond pads; a stress buffer layer, comprising:\n a plurality of pads laterally distributed over an IC die in an IC package, each of the plurality of pads having a proximal end contacting one of the non-electrically conducting surfaces of the IC die, and having a distal end opposite each proximal end of each the plurality of pads; and \n a plurality of posts laterally distributed directly on each of the plurality of pads, each of the plurality of posts having a proximal end contacting respective distal ends of each pad of the plurality of pads, and having a distal end opposite each proximal end of each of the plurality of posts, wherein each post has a lateral width less than a lateral width of its corresponding pad; and \n a heat spreader having a proximal surface contacting the distal ends of the plurality of posts, and having a distal surface exposed from the IC package.
