IPC: H01L29/74
Filed: 1980-03-05
Abstract: PURPOSE:To control increase of voltage even if blocking voltage were to be impressed for a long period of time, by connecting respective collector electrodes to main electrodes on two main surfaces of a semiconductor substrate on which a p-n joint is exposed onto the side surface. CONSTITUTION:A p type emitter 1 and a p type base 3 are dispersed onto an n type Si 2, and an n type emitter 4 is selectively formed on the p layer 3. An anode 5 is formed on a main surface 101, a cathode 6 and a control electrode 7 are formed on a main surface 102, and the layer 3 and 4 are shortcircuited by the cathode 6 in a region 41. Further processing is done so that a side surface 103, where a p-n joints J1 and J2 are exposed, becomes positive level. Collector electrodes 8 and 9 which have ohmic connections to the electrodes 5 and 6, are provided in terminal regions 300 and 400 of a substrate, they are made to stick out from circumferencial edge of the main surface so that outside edges 8a and 9a become cylindrical, and they are made to close each other. The circumferencial section is covered by an Si rubber type protective membrane 200. In this mechanism, even if a high blocking voltage were to impressed for a long period of time, amount of impurity to be accumulated on surface of a semiconductor layer is small, and therefore, it is possible to obtain a device of low leak current and stable blocking characteristic.
