ABSTRACT:
A semiconductor device including a diode and a bipolar transistor which are connected to each other and formed in an isolated area of a semiconductor layer has a diffused region formed between a base region of the bipolar transistor and a formation region of the diode across the isolated area. The diffused region has the same conductivity type as that of the base region, so that a PNPN diode effect does not occur.
