Patent ID: 7038310

Claim:
A power module comprising: an insulating layer comprising an inorganic filler and a thermosetting resin composition; a lead formed on one side of the insulating layer; a heat sink formed on another side of the insulating layer; at least one semiconductor chip sealed in the insulating layer and electrically connected with a buried side of the lead by flip-chip bonding; an electronic component that is not sealed within the insulating layer, and is electrically connected and mounted to an exposed side of the lead that is opposite to the buried side of the lead on which the at least one semiconductor chip is disposed; and at least one portion of the insulating layer is interposed between the semiconductor chip and the heat sink; wherein the semiconductor chip and the heat sink are electrically insulated from each other; the at least one semiconductor chip is disposed between the heat sink and the lead; and the lead is buried in the insulating layer while a part thereof is exposed at the surface of the insulating layer.
