THERMAL MANAGEMENT SOLUTIONS FOR INTEGRATED CIRCUIT ASSEMBLIES USING PHASE CHANGE MATERIALS

An integrated circuit structure may be formed using a phase change material to substantially fill at least one chamber within the integrated circuit assembly to increase thermal capacitance. The integrated circuit assembly may comprise a substrate, at least one integrated circuit device electrically attached to the substrate, a heat dissipation device, a thermal interface material between the integrated circuit device and the heat dissipation device, a chamber defined by the heat dissipation device, the substrate, and the integrated circuit device, and a phase change material within the chamber.
