Abstract:
An integrated circuit package having excellent heat dissipation is described. An integrated circuit die is attached to a substrate and the substrate is mounted on a printed circuit board (PCB) wherein there is a gap between a surface of the die facing the PCB and the PCB. A thermal enhanced layer is formed within the gap wherein heat travels from the die through the thermal enhanced layer to the PCB.
