摘要： A composite of two or more thermal interface materials (“TIMs”) is placed between a die and a heat spreader to improve cooling of the die in an integrated circuit package. The two or more TIMs vary in heat-dissipation capability depending upon the locations of die hot spots. In an embodiment, a more thermally conductive material may be positioned over one or more die hot spots, and a less thermally conductive material may be positioned abutting and/or surrounding the more thermally conductive material. The two or more TIMs may comprise a solder and a polymer. The composite TIM may be preformed as one unit or as a plurality of units. Methods of fabrication, as well as application of the package to an electronic assembly and to an electronic system, are also described.

摘要： A device and method for designing and manufacturing an integrated heat spreader so that the integrated heat spreader will have a flat surface on which to mount a heat sink after being assembled into a package and exposed to the heat of a die. This device and method for designing and manufacturing an integrated heat spreader would generate a heat spreader that would be built to compensate for deformations resulting from (1) physical manipulation during assembly, (2) thermal gradients during operation, and (3) differing rates of expansion and contraction of the package materials coupled with multiple package assembly steps at elevated temperatures so that one surface of the integrated heat spreader would have a flat shape.

摘要： An electronic assembly is provided having a die, a heat spreader, and a solidified solder material. A die includes a die substrate and an integrated circuit on a bottom surface of the die substrate. The heat spreader is located above the die and has left and right inclined faces. The left inclined face tapers from a point near a center of the die to a point upward and to the left of the upper surface. The right inclined face tapers from a point near the center upward and to the right above the upper surface. A solidified solder material fills regions between the upper surface and the inclined faces of the lower surface.
