ABSTRACT:
A transistor of a semiconductor device has an increased driving capacity. The semiconductor device has a first gate insulation film formed by a selective oxidation, a second gate insulation film formed by thermal oxidation and a gate electrode formed across the first and the second gate insulation films. The second gate insulation film is composed of a thicker gate insulation film and a thinner gate insulation film.
