Abstract: PURPOSE: To ignore the base series resistance of a parasitic perpendicular bipolar transistor by adjusting an ion implantation energy so that the peak of the dopant concentration of a heavily doped part of a body region is located on the lower side of a source region than the surface of a semiconductor layer. CONSTITUTION: With an insulation gate layer 10 on the surface of a semiconductor layer 3 as a mask, a first impurity is ion-implanted with an energy in a specific thickness from the surface of the semiconductor layer 3 and is thermally diffused, thus forming a body region 2 consisting of a first greatly doped part 5 that is nearly aligned to both edges of the insulation layer 10 and a horizontal diffusion part 6 at the lower side of the insulation layer 10. The second impurity is ion-implanted selectively into the body region 2 in a pair, thus forming an annular source 7 that is aligned to both edges of the insulation layer 10, thus forming the greatly doped part 5 of the first impurity so that it is located at the lower side of the annular source region 7 and ignoring the base series resistance of a parasitic perpendicular bipolar transistor.

Abstract: PURPOSE: To stabilize the operational characteristics by entirely covering the projecting end of an insulating pocket with a first grounded metallization part. CONSTITUTION: In order to overcome voltage rise at an insulation pocket P caused by the presence of a parasitic transistor, projecting end of the insulating pocket is covered entirely with a metallization part 21, e.g. a metal polysilicide, preferably a platinum layer. It has a resistance of about 1Ω/square which is about 100 times as low as that of the insulation pocket P. Some region of the insulation pocket Preaches a grounded metal track of aluminum and comes into contact therewith. Since the leakage current of parasitic transistors T3, T4 is passed through a low resistance path and grounded, it causes no voltage rise at the insulation pocket P.
