Patent number: 6262474Abstract: A semiconductor device is formed of a casing, a substrate situated in the casing, at least one semiconductor chip fixed on the substrate, and at least one lead-out terminal for connecting the semiconductor chip to outside. The lead-out terminal includes a soldered portion soldered to the substrate, and a fixed portion fixed to the casing. A stress relaxing device or cutout is formed between the soldered portion and the fixed portion of the lead-out terminal to relieve stress along three axial directions orthogonal to each other. Thus, the crack formation is prevented in the soldered portion of the lead-out terminal while the resistance and impedance of the lead-out terminal are maintained at low values.Type: GrantFiled: April 29, 1999Date of Patent: July 17, 2001Assignee: Fuji Electric Co., Ltd.Inventors: Takatoshi Kobayashi, Souichi Okita, Rikihiro Maruyama
