Abstract: Provided is a semiconductor module including a main circuit portion, a plurality of circuit electrodes, a plurality of main terminals, and a plurality of wires, in each of semiconductor chips, transistor portions and diode portions have a longitudinal side in a second direction, each of semiconductor chips has a plurality of end sides including a gate-side end side, each of the gate-side end sides is arranged facing a same side in a top view, the plurality of main terminals are arranged on a same side in relation to the main circuit portion so as not to sandwich the main circuit portion in a top view, each of the plurality of wires has a bonding portion, and a longitudinal direction of the bonding portion has an angle in relation to the second direction.

Abstract: In a semiconductor device, when a printed circuit board is pressed against a bottom part of a case with an adhesive interposed therebetween, the back surface of the printed circuit board is supported by projections formed on the bottom part. Since the gap between the printed circuit board and the bottom part is maintained to have substantially the same height as the projections, the adhesive pressed by the printed circuit board does not spread excessively. At each edge of the printed circuit board in the long-side direction, the end of the adhesive is aligned with or extends slightly beyond the edge. In the short-side direction, the adhesive extends beyond each edge of the printed circuit board, but does not extend over the front surface of the printed circuit board, internal connection terminals, or the front surface of a ceramic circuit board.

Abstract: Aspects of the invention provide a semiconductor module that can be manufactured without using a bending jig for bearing the stress in bending process of the terminal and scarcely generates cracks in the resin parts of the semiconductor module. In some aspects of the invention, a semiconductor module can include a casing made of a resin material accommodating a semiconductor chip, a terminal one end of which is electrically connected to the semiconductor chip and the other end of which is projecting out of the casing and bent and a lid made of a resin material fitted on an opening of the casing, a part of end region of the lid being in contact with the terminal and being a thick part with a thickness thicker than a thickness of other parts of the lid.
