Stacked silicon package assembly having thermal management using phase change material

Abstract:

A chip package assembly and method for fabricating the same are provided which incorporate phase change materials within the chip package assembly for improved thermal management. In one example, a chip package assembly is provided that includes a substrate, a first integrated circuit (IC) die stacked on the substrate, a dielectric filler layer, a cover and a phase change material. The phase change material is sealed within a recess formed between the first IC dies and the cover.
