Patent JP-H01181450-A (JP)
Title: Resin sealed semiconductor device
Inventor: KONO RYUJI
IPC: H01L23/28
Filed: 1988-01-11
Abstract: PURPOSE:To prevent the generation of resin cracks, by constituting the lower surface of a tab and the lower surface of a device close to an element at the central part of the tab, while constituting them as a curved surface distant from the element, or a synthesized shape of planes, or a synthesized shape of a curved surface and a plane, at the periphery. CONSTITUTION:An element 1 is mounted on a bent tab 3a via an adhesive agent 2. These are sealed with a resin 5, in the lower part of which a bent part 5a is formed. Resin cracks of lower corner part of the tab are generated by large tensile stress of the lower corner parts of the tab caused by the exfoliation of a boundary surface between the lower surface of the tab and the resin, and vapor pressure generating at this part. Since the resin 5 under the lower surface of the tab is bent, according to the same principle as the arch of a dam, the tensile stress generating in the resin 5 caused by a pressure from above is reduced. As a result, the dielectric strength is increased as compared with conventional plane type, and further the expansion of the boundary surface can be restrained, thereby preventing the resin cracks of the boundary surface.
