Patent ID: 8232637

Claim:
A power module comprising: an insulated metal substrate (IMS) comprising: a circuit layer comprising an insulator material including metallized circuitry integrated therein and a first plurality of thermal vias disposed there through; an insulator layer comprising a first surface bonded to a first surface of the circuit layer; and a metal base layer bonded to a second surface of the insulator layer opposite the first surface of the insulator layer, the metal base layer comprising a plurality of cooling fluid channels integrated therein; and at least one semiconductor power device bonded to a second surface of the circuit layer opposite the first surface of the circuit layer; wherein each semiconductor power device comprises a corresponding case with external electrical contacts, and further wherein each semiconductor power device case abuts a corresponding plurality of thermal vias selected from within the first plurality of thermal vias, and further wherein the first plurality of thermal vias are spaced apart from the semiconductor power device external electrical contacts.
