Patent number: 4958215Abstract: A press-contact flat type semiconductor device is disclosed which, without alloy-bonding a silicon pellet to a molybdenum or tungsten disc, assures a uniform press contact because a warp on the silicon pellet is largely reduced in comparison with a conventional device. A silver sheet is omitted between an anode electrode post and the silicon pellet to absorb a warp on the pellet. It is only necessary to insert a molybdenum or tungsten disc there, instead, which is thinner than a counterpart of the conventional device.Type: GrantFiled: July 25, 1989Date of Patent: September 18, 1990Assignee: Kabushiki Kaisha ToshibaInventors: Shinjiro Kojima, Hideo Matsuda, Masami Iwasaki, Yoshinari Uetake
