Patent number: 10403559Abstract: In a power semiconductor device, the thickness dimension of a protective film of a semiconductor element is made smaller than that of an upper electrode, so a protective film is not pressed by being pressurized from upward when bonded by a metal sintered body, and the force of tearing off the upper electrode riding on an inclined surface of the protective film does not act, so that no crack of the upper electrode occurs, thus maintaining the soundness of the semiconductor element. Also, a lead bonded by a solder to the upper electrode of the semiconductor element is made of a copper-Invar clad material, the linear expansion coefficient of which is optimized, and thereby it is possible to realize a durability superior to that of a heretofore known wire-bonded aluminum wiring.Type: GrantFiled: May 26, 2016Date of Patent: September 3, 2019Assignee: Mitsubishi Electric CorporationInventors: Masaru Fuku, Noriyuki Besshi, Ryuichi Ishii, Takayuki Yamada, Takao Mitsui, Komei Hayashi
