Patent ID: 8659150

Claim:
A semiconductor module, comprising: a semiconductor device comprising: a semiconductor substrate, a first electrode formed on one surface of the semiconductor substrate, and a second electrode formed on a surface of the semiconductor substrate opposite to the one surface; a first electrode plate being in contact with the first electrode, a second electrode plate being in contact with the second electrode, a cylinder encompassing the semiconductor device and the second electrode plate, the cylinder being fixed to the first electrode plate, a first thread groove is formed on one of an outer peripheral surface or an inner peripheral surface of the cylinder; a cover on which a second thread groove is formed, the cover being fixed to the cylinder by an engagement of the first thread groove and the second thread groove, and the cover pressurizing the second electrode plate and the semiconductor device via an insulating member for the cover; and a first wiring member extending outward from a space between the first electrode plate and the cover, wherein one end of the first wiring member is connected to the second electrode plate and another end of the first wiring member penetrates the first electrode plate at a first penetration region and is insulated from the first electrode plate at the first penetration region; wherein the first electrode plate, the semiconductor device, and the second electrode plate are fixed with each other by an application of a pressure to the first electrode plate, the semiconductor device, and the second electrode plate by fastening the first thread groove and the second thread groove.
