Abstract
A method of manufacturing a semiconductor device, comprising forming a semiconductor region of a type of conductivity that is attached to a surface of a semiconductor body, wherein most of the concentration of impurities of said conductivity type of a part of the region next to the surface is obtained by a process different from that of the ion implantation, characterized in that impurification ions characteristic of said type of conductivity are implanted through the surface of the semiconductor body to provide the greater part of the concentration of impurities of said conductivity type of a substantially substantially layered part, away from the surface, of the region extending substantially parallel to the surface of the semiconductor body, located under said part adjacent to the surface forms a pn junction with an underlying semiconductor body part of the opposite conductivity type, and s e for said part adjacent to the surface of said unión p-n.
