Patent ID: 7372146

Claim:
A semiconductor module, comprising: a package substrate; a first power switching device chip having electrodes on a top surface and on a back surface, configured to flow current between said electrodes, and being mounted above said package substrate while letting said top surface face said package substrate; a second power switching device chip having electrodes on a top surface and on a back surface, configured to flow current between said electrodes, and being mounted above said package substrate while letting said top surface face said package substrate; an integrated circuit (“IC”) chip mounted above said package substrate, configured to drive gates of transistors formed in said first and second power switching device chips; a first heat sink disposed above said electrode on said back surface of said first power switching device chip, a second heat sink disposed above said electrode on said back surface of said second power switching device chip, and a resin member configured to seal said first and second power switching device chips and said IC chip as a single package, wherein said electrode on said back surface of said first power switching device chip is electrically connected to said electrode on said top surfaces of said second power switching device chip via said first heat sink.
