ABSTRACT:
A transistor having a semiconductor substrate of a first conductivity type, a base region of a second conductivity type formed in the semiconductor substrate, a source region of the first conductivity type, a gate electrode formed on the base region between the source region and the semiconductor substrate via a gate insulator film, an additional region of the second conductivity type formed in the semiconductor substrate but separated from the base region, a resistive layer formed in electrical contact with an area of the semiconductor substrate which is separated from the base region and the additional region, a source electrode connected with the source region and a drain electrode connected with the additional region and the resistive layer.
