Abstract

PURPOSE:To prevent the generation of an N channel by forming a P<+> type high concentration impurity region to the surface except an element forming region of a P type Si base body. CONSTITUTION:An N type base region 14 and a P<+> type emitter region 15 are shaped to the P type Si base body 11 manufactured by forming a P type epitaxial layer 13 onto a P<+> type Si substrate 12. The P<+> type high concentration impurity region 16 (the region 16 may be isolated slightly from the base region 14) is molded to the surfaces of other regions. Accordingly, the generation of the N channel in the interface with an Si oxide film 17 can be prevented.
