Abstract
PURPOSE:To prevent an influence by a parasitic MOS without expanding an area to be occupied by an element to be used such as a transistor or the like by a method wherein an upper part of a region surrounded by a region corresponding to a drain and a source of the parasitic MOS is covered with an electrode whose potential is identical to the region. CONSTITUTION:A source 7 and a drain 7' of a PMOS are formed; however, a collector wiring part 12 of an NPN transistor is formed and is taken out to an upper part in such a way that an Al wiring part is connected to an electrode 14 connected electrically to a collector contact 9; the electrode 14 connected to the collector contact 9 of the NPN transistor covers an upper part of an N-type epitaxial layer 3 in a collector region; this N-type epitaxial layer 3 and the electrode 14 are at an identical potential; accordingly, the surface of the N-type epitaxial layer 3 is not reversed electrically; even when a potential of the wiring part 12 other than a collector wiring part on the surface of a substrate 1 is selected arbitrarily, a parasitic MOS does not become an ON state; thereby a base layer 6 and an isolation layer 4 do not become a conductive state.
