Patent ID: 7071550

Claim:
A semiconductor module comprising: a package substrate with a plurality of terminals and a wiring line connected to said terminals; a plurality of power switching device chips having a first electrode on top surfaces and a second electrode on back surfaces, configured to flow current between said first and second electrode, and being mounted above said package substrate while letting said top surfaces face said package substrate; a drive-use integrated circuit (“IC”) chip mounted above said package substrate, configured to drive gates of transistors formed in said-plurality of power switching device chips; a plurality of heat sinks disposed above said second electrode on said back surfaces of said plurality of power switching device chips, electrically connected to said second electrode on said back surfaces and said terminals of said package substrate, and serving as a wiring line to said plurality of power switching device chips; and a resin member configured to seal said plurality of power switching device chips and said drive-use IC chip as a single package.
