摘要: An improved process for the manufacture of a semiconductor device having a plurality of bipolar type semiconductor elements formed on a substrate and isolated from each other by diffusion layers. Each diffusion layer is formed by a diffusion layer diffused from an impurity source buried in the substrate into a semiconductor layer epitaxially grown on the substrate and another diffusion layer diffused from the surface of the epitaxially grown semiconductor layer until it is combined with the first-mentioned diffusion layer.

摘要: Manufacturing of power semiconductor devices utilizing a metal strip and a lead frame. The metal strip has a plurality of portions on which semiconductor chips are mounted, and fastening means constituted by indents at the longer sides of the strip and metal pieces protruding along the indents. The lead frame has a plurality of lead units and tab portions corresponding to the indents. The lead frame is locked over the metal strip by inserting the tab portions into the corresponding indents and bending the metal pieces toward the tab portions. After encapsulating the combinations of the lead units and the portions having the chips thereon with plastic material, respectively, the metal strip and the lead frame are cut along the portions of the tab-metal piece combinations, thereby to obtain a plurality of individual power semiconductor devices.
