Patent number: 5513072Abstract: In the present invention, a heat spreader, circuit boards for power semiconductor elements, and a circuit board for a control circuit are fixed on a metal plate. The heat spreader is made of an IMS. The IMS has a metal base made of Cu or Cu clad plate, and a high heat radiating insulating layer made of a resin-based material, and the metal plate and the heat spreader are adhered by the high heat radiating insulation layer and electrically insulated from each other. Only a power semiconductor element is soldered onto the heat spreader. A wiring pattern for guiding each terminal of the power semiconductor element to the outside is formed on a power circuit board. A control circuit for controlling the power semiconductor element is formed on the circuit board for the control circuit.Type: GrantFiled: November 18, 1994Date of Patent: April 30, 1996Assignee: Kabushiki Kaisha ToshibaInventors: Yoshiaki Imaji, Satoshi Nakao, Hiroshi Sawano

Patent number: 5055912Abstract: A semiconductor device mounted on a substrate. Outer leads, partially resin-molded, have a greater height above the mounting surface than that of a conventional device. Specifically, each lead projecting from the molded resin has a bent portion which is convex in the direction opposite to the mounting surface, and the length of the lead beyond the bent portion is greater than the distance from the lead portion adjacent to the resin portion of the lead to the mounting surface. The long leads improve reliability during, e.g., heat cycle, tests. In another embodiment, outer leads, partially resin-molded, have reverse J-shaped bent portions, each with a distal end positioned away from the resin. When the bent portions serve as soldering portions, the soldering condition can be easily checked.Type: GrantFiled: September 4, 1990Date of Patent: October 8, 1991Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Yasuhiro Murasawa, Hitoshi Toda, Hiroshi Sawano, Hideya Yagoura
