Abstract:
1. A semiconductor device comprising: a semiconductor chip mounting substrate including a substrate, a semiconductor chip provided on a first major surface of the substrate, and a first and second semiconductor chip connection electrodes; a control circuit board provided generally in parallel to the first major surface and including a control circuit configured to control the semiconductor chip, a control signal terminal connected to the control circuit, and a through hole extending in a direction generally perpendicular to the first major surface; a power terminal holder provided on opposite side of the control circuit board from the semiconductor chip mounting substrate and including a power terminal serving for at least one of input and output of power of the semiconductor chip; and a semi-fixing member including a shank portion and an end portion, the shank portion being fixed to the power terminal holder and penetrating through the through hole, a cross section of the shank portion in a plane orthogonal to the extending direction of the through hole being smaller than a size of the through hole, the end portion being connected to a tip of the shank portion, a cross section of the end portion in a plane orthogonal to the extending direction of the through hole being larger than the size of the through hole, the first semiconductor chip connection electrode being connected to a first terminal of the semiconductor chip and the control signal terminal, and the second semiconductor chip connection electrode being connected to a second terminal different from the first terminal of the semiconductor chip and the power terminal, wherein the tip is an end of the shank portion on the semiconductor chip mounting substrate side.
