Abstract

PURPOSE: To obtain a transistor of high hFE and fT by forming an n-type epitaxial layer on a substrate containing As and B, forming a p-type layer in the opitaxial layer, then surrounding the n-type region with a p-type collector layer and further forming a p-type emitter region by means of selfer line.
