Abstract

A semiconductor module includes a semiconductor device, a first conductive member, a second conductive member, a cylinder, and a cover. The first conductive member is in contact with a first electrode of the semiconductor device. The second conductive member is in contact with a second electrode of the semiconductor device. The cylinder encompasses the semiconductor device and is fixed to the first conductive member, and a first thread groove is formed on the cylinder. A second thread groove is formed on the cover. The cover is fixed to the cylinder by an engagement of the second thread groove with the first thread groove. The semiconductor device and the second conductive member are fixed by being sandwiched between the first conductive member and the cover. The second conductive member includes a portion extending from inside to outside the cylinder by penetrating an outer peripheral wall of the cylinder.

Claims (19)

1. 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 cylinder encompassing the semiconductor device and fixed to the first conductive member, and on an outer peripheral surface or an inner peripheral surface of which a first thread groove is formed; and

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,

wherein the semiconductor device and the second conductive member are fixed by being sandwiched between the first conductive member and the cover, and

the second conductive member comprises an extending portion extending from inside the cylinder to outside the cylinder by penetrating an outer peripheral wall of the cylinder which is located on a side of the first conductive member with respect to the cover.

2. A semiconductor module of claim 1 , further comprising:

a third electrode formed on the one surface of the semiconductor substrate; and

a third conductive member being in contact with the third electrode and extending from inside the cylinder to outside the cylinder by penetrating the outer peripheral wall of the cylinder which is located on the side of the first conductive member with respect to the cover.

3. A semiconductor module of claim 1 , further comprising:

a first cooler connected to a surface of the first conductive member which is opposite to the semiconductor device; and

a second cooler connected to a surface of the cover which is opposite to the semiconductor device.

4. A semiconductor module of claim 1 , further comprising an insulating member located between the third conductive member and the first conductive member,

wherein the third conductive member is fixed by being sandwiched between the third electrode and the insulating member.
