Patent ID: 7759778

Claim:
A leaded semiconductor power module, comprising: a first heatsink having an electrically insulative inboard face; at least one conductor pad formed on said insulative inboard face and defining a mounting surface; at least one semiconductor chip having first and second faces on which are formed first and second terminals, respectively, said first face being directly attached to said mounting surface such that said first terminal is electrically coupled to said conductor pad; a leadframe substrate having a first segment directly attached to the second face of said semiconductor chip such that said first segment is also electrically coupled to the second terminal of semiconductor chip, and a second segment directly attached to said mounting surface such that said second segment is also electrically coupled to said conductor pad; a second heatsink thermally coupled to the leadframe substrate but electrically insulated therefrom; and a molded encapsulant that exposes outboard surfaces of the first and second heatsinks, and lead ends of said first and second segments.
