Abstract

PURPOSE: To increase further the dielectric strength of a high dielectric strength transistor, by turning the base-collector junction surface down to use it as the concaved surface of a convexity and making cross the concaved surface the second mesa ethed curved surface at the curved side surface other than the flat surface of the concave surface.
