Abstract
The present invention provides an electric circuit device in which it is possible to achieve simultaneously the improvement of cooling performance and reduction in operating loss due to line inductance.The above object can be attained by constructing multiple plate-like conductors so that each of these conductors electrically connected to multiple semiconductor chips is also thermally connected to both chip surfaces of each such semiconductor chip to release heat from the chip surfaces of each semiconductor chip, and so that among the above conductors, a DC positive-polarity plate-like conductor and a DC negative-polarity plate-like conductor are opposed to each other at the respective conductor surfaces.
