Abstract:
1. A cooling structure for an integrated circuit structure having multiple integrated circuit chips, said cooling structure comprising: a plurality of heat spreaders having different thicknesses, wherein the lower side of each of said heat spreaders is connected to the top of a corresponding one of said integrated circuit chips; and a heat dissipating structure having a flat base connected to the upper sides of said heat spreaders through a thermally conductive material, wherein said thermally conductive material is positioned in gaps between the upper sides of said heat spreaders and said flat base of said heat dissipating structure, and wherein the smallest of said gaps exists between the top of the thickest of said heat spreaders that is connected to the integrated circuit chip that produces the most thermal energy, relative to the other integrated circuit chips, and said flat base of said heat dissipating structure.
