More Information
Summary:An electric circuit device comprises a plurality of semiconductor chips (111) and a plurality of plate-shaped conductors (120, 130, 140) electrically connected to said plurality of semiconductor chips, wherein said plurality of plate-shaped conductors are constructed such that both chip surfaces of each of said plural semiconductor chips are each thermally connected to one of said plurality of plate-shaped conductors in order to release heat from both chip surfaces of each semiconductor chip through said plate-shaped conductor, and such that among said plurality of plate-shaped conductors, a plate-shaped conductor (130) for direct-current positive polarity and a plate-shaped conductor (140) for direct-current negative polarity are opposed to each other.
