Abstract
It is an object to provide a technique allowing for suppression of the height of a protrusion from the surface of a semiconductor module. A semiconductor device includes: a semiconductor module having a first groove; a Belleville washer having a recess in an outer surface and a protrusion on an inner surface; and a screw passing through the hole of the Belleville washer and the first groove of the semiconductor module to fasten the semiconductor module and an attached body. A head of the screw is accommodated in the recess of the Belleville washer, and at least portion of the protrusion of the Belleville washer is accommodated in the first groove of the semiconductor module.
Claims17
A semiconductor device comprising:
- a semiconductor module having a first groove;
- a Belleville washer whose hole and a periphery of the hole are recessed to have a recess in an outer surface and a protrusion on an inner surface;
- and
- a screw passing through the hole of the Belleville washer and the first groove of the semiconductor module to fasten the semiconductor module and an attached body, wherein
- a head of the screw is accommodated in the recess of the Belleville washer, and
- at least portion of the protrusion of the Belleville washer is accommodated in the first groove of the semiconductor module.
A semiconductor device comprising:
- a semiconductor module;
- a Belleville washer;
- and
- a screw passing through a hole of the Belleville washer to fasten the semiconductor module and an attached body, wherein
- the semiconductor module has a groove to accommodate an outer periphery of the Belleville washer.
A semiconductor device comprising:
- a semiconductor module;
- and
- a screw having a threaded portion integrated with a Belleville washer, and fastening the semiconductor module and an attached body.
A semiconductor device comprising:
- a semiconductor module having an electrode terminal protruding laterally;
- a Belleville washer disposed on an upper surface of the semiconductor module;
- a cover including a first portion opposing the electrode terminal and a second portion opposing the upper surface and protruding upward from the first portion to accommodate the Belleville washer, the second portion pressing the Belleville washer toward the semiconductor module;
- and
- a screw to fasten the first portion of the cover, the electrode terminal of the semiconductor module, and an attached body.
