Abstract: A method and apparatus for making the weight load distribution more uniform over the surface of a processor die and improving the heat transfer between the processor die and a thermal spreader cap is provided. The apparatus includes generally a square-like box shaped thermal spreader cap having a cavity that conforms to the shape of the processor die. The thermal spreader cap fits over the processor die and has a cavity that is dome-like in shape. Additionally, the thermal spreader cap is attached to a thermal dissipative device which may in turn be connected to a heat sink. The apparatus provides a thinner and more uniform thermal interface layer between the processor die and the thermal spreader cap, thereby evening the weight load on the surface of the processor die and improving the heat flux between the processor die and the thermal spreader cap.
