THERMAL MANAGEMENT OF INTEGRATED CIRCUITS USING PHASE CHANGE MATERIAL AND HEAT SPREADERS

At least one feature pertains to an apparatus having passive thermal management that includes an integrated circuit die, a heat spreader thermally coupled to the integrated circuit die, a phase change material (PCM) thermally coupled to the heat spreader, and a molding compound that encases the heat spreader and the PCM. In one example, the heat spreader may include a plurality of fins, and at least a portion of the PCM is interposed between the plurality of fins. Another feature pertains to an apparatus that includes an integrated circuit die, and a molding compound having a phase change material intermixed therein. The resulting molding compound completely encases the die.
