Abstract

PURPOSE: To prevent the deterioration in the boundary state of an oxide film for field, by producing the oxide film at such a thickness that the film does not reach a semiconductor substrate and causing an impurity to creep up to a semiconductor layer located between the substrate and the oxide film so that a channel cut region is produced.
CONSTITUTION: The oxide film 3 for field is produced at such a thickness by thermal oxidation on the surface of the semiconductor layer 2 epitaxially grown on the semiconductor substrate 1 that the oxide film 3 does not reach the substrate 1. The impurity is caused to creep up to the semiconductor layer located between the substrate 1 and the oxide film 3 so that the channel cut region is produced. The deterioration in the boundary state of the oxide film for field can thus be prevented.
