Abstract
PURPOSE: To increase the drain dielectric strength without decreasing gm, by making thicker th e gate insulation film near the both or one region of the source and drain ragions than the gate insulation film of other regions, and by providing a region of opposite conduction type having higher concentration than the impurity concentration of the substrate immediately under the thicker insulating film.
