Abstract
PURPOSE: To provide semiconductor pellet for heatsink type semiconductor device, having a highly economical and efficient electrode structure, by forming a two- layer electrode structure consisting of metal film covering and metal piece.
CONSTITUTION: Collector layer 21, base layer 22 and emitter layer 23 are formed on a semiconductor base by the selective diffusion method, for example. A hole for forming an electrode is provided on SiO2 film coating 24. Emitter electrode film coating 32 and base electrode film coating 34 are formed by evaporating Cr-Ni-Ag, for example. Next, window-fitted emitter electrode piece 41 base electrode piece 51 of proper size and shape are fixed to electrode film coatings 32 and 33 by using Pb-Sn-Ag solder, for example. By this, the thickness of electrode pieces can be selected freely, and at the same time, efficient electrodes can be formed. Consequently, it is possible to provide a sufficient thickness so as to prevent electric discharge.
