Abstract
A power module package structure includes, from top to bottom, a layer of power chips, an upper bonding layer, a thermally-conductive and electrically-insulating composite layer, and a heat dissipation layer. The thermally-conductive and electrically-insulating composite layer contains an insulating layer and an upper copper layer that is formed on the insulating layer. One or more layers of upper packaging materials are covered over the layer of power chips and the upper bonding layer and are in contact with an upper surface of the upper copper layer. One or more layers of lower packaging materials are in contact with the insulating layer and are in contact with sidewalls of the upper copper layer. The lower packaging material has a higher rigidity than the upper packaging material.
