Assignee: FUJI ELECTRIC CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a semiconductor module having
at least one semiconductor assembly composed of
a multilayer substrate which includes an insulating substrate, and an electrically conductive plate having edges to form a rectangular shape and provided at a bottom surface side of the insulating substrate, and
a semiconductor element mounted on the multilayer substrate, and

a sealing part which seals the at least one semiconductor assembly except a bottom part of the electrically conductive plate;

a cooler which has a mounting surface on which the semiconductor module is mounted; and
a heat conduction sheet which is placed between the semiconductor module and the mounting surface of the cooler and is in contact with the bottom part of the electrically conductive plate,
wherein the heat conduction sheet has a recess corresponding to at least one edge of the electrically conductive plate and placed under the at least one edge of the electrically conductive plate, and only a bottom part of the at least one edge is entered in the recess along a whole length of the at least one edge.
