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 9):
A method for manufacturing a heat dissipation structure for use in dissipating heat within an integrated circuit (IC) package, the method comprising:\n depositing a first mask layer over an IC die within the IC package; removing areas of the first mask layer to create first openings exposing corresponding non-electrically conducting surfaces of the IC die; forming a pad in each of the first openings over the exposed corresponding non-electrically conducting surfaces of the IC die and to a height of the first mask layer; depositing a second mask layer over each pad and remaining portions of the first mask layer; removing areas of the second mask layer to create second openings, each exposing only a part of a corresponding pad; forming a post in each of the second openings directly on the exposed part of each corresponding pad; removing the first and second mask layers; depositing a dielectric material over the IC die, pads, and posts to a height of the posts; and forming a heat spreader on the dielectric material and the posts, and with a distal surface of the heat spreader exposed from the dielectric material.
