Patent ID: 8786107

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 conductive member being in contact with the first electrode; a second conductive member being in contact with the second electrode; a third conductive member being in contact with the second conductive member and extending along the first conductive member; and an insulating member insulating between the first conductive member and the third conductive member, wherein the third conductive member is fixed to the first conductive member and the second conductive member by being sandwiched between the first conductive member and the second conductive member and extends to outer side of the second conductive member, the semiconductor module further comprises a cylinder formed of an insulator, encompassing the semiconductor device, fixed to the first conductive member, and having a first thread groove formed on an outer peripheral surface thereof, the semiconductor device is fixed to the first conductive member and the second conductive member by being sandwiched between the first conductive member and the second conductive member and is disposed at a position inside the cylinder, and a second thread groove is formed on the second conductive member, and the second conductive member is fixed to the cylinder by an engagement of the first thread groove and the second thread groove.
