Claim Text:
1. A semiconductor module adapted to be packaged on a substrate, the semiconductor module comprising: a semiconductor chip that has a switching function; a resin portion that is formed to cover the semiconductor chip, wherein: the resin portion includes a first surface side and a second surface side, which are opposed to each other and extend generally in parallel to an imaginary plane; and the substrate is located on the first surface side of the resin portion; a gate terminal, a source terminal, and a drain terminal that are bonded to the semiconductor chip and project from the resin portion in a direction of the imaginary plane and that are soldered onto the substrate; and a heat dissipation portion that is disposed on the second surface side of the resin portion to release heat generated in the semiconductor chip, wherein: both the source terminal and the drain terminal are physically directly connected to the heat dissipation portion; and at least one particular terminal of the source terminal and the drain terminal is electrically connected directly to the heat dissipation portion, wherein the heat dissipation portion parallel to the imaginary plane has a cross-sectional area, and the resin portion parallel to the imaginary plane has a cross-sectional area, and wherein the cross-sectional area of the entire heat dissipation portion parallel to the imaginary plane is larger than the cross-sectional area of the entire resin portion parallel to the imaginary plane.
