Patent ID: 7514783

Claim:
A semiconductor module, comprising: a mounting board formed to be a rectangle in shape with four sides; a plurality of power switching device chips each having an upper surface and a lower surface and mounted on said mounting board by flip-chip bonding with said upper surface faced toward said mounting board; a drive IC chip mounted on said mounting board by flip-chip bonding and operation to drive gates of transistors formed in said plurality of power switching device chips; a plurality of heat sink members located respectively on said lower surfaces of said plurality of power switching device chips; a resinous member provided to seal said plurality of power switching device chips and said drive IC chip in a single package; and a power source terminal and a ground terminal of a circuit configured by said plurality of power switching device chips, wherein said power source terminal is located at one of two adjacent perpendicular sides of said rectangle, and said ground terminal is located at the other adjacent perpendicular side; and wherein said heat sink member services as a wire that connects said power switching device and said mounting board; and further comprising a decoupling condenser connected between said power source terminal and said ground terminal.
