Patent number: 8324726Abstract: A semiconductor device that improves the heat cycle resistance and power cycle resistance of a power module. An electrode member in which copper posts are formed in a plurality of perforations cut in a support made of a ceramic material is soldered onto a side of an IGBT where an emitter electrode is formed. By soldering the copper posts onto the electrode, heat generated in the IGBT is transferred to the electrode member and is radiated. In addition, even if a material of which the IGBT is made and copper differ in thermal expansivity, stress on a soldered interface is reduced and distortion is reduced. This suppresses the appearance of a crack. As a result, the heat cycle resistance and power cycle resistance of a power module can be improved.Type: GrantFiled: February 10, 2006Date of Patent: December 4, 2012Assignees: Octec, Inc., Fuji Electric Co., Ltd., Kyocera CorporationInventors: Katsuya Okumura, Yoshikazu Takahashi, Kazunori Takenouchi
