Abstract

PURPOSE:To prevent the lowering of property in the low current area by cutting the current flowing over the surface of the Step Cut type SIT while the channel of the current flowing horizontally by means of the floating gate, the cut, the oxide insulator and the like. CONSTITUTION:Cut sections are provided on the surface of a semiconductor 1, having grooves parallel with each other. An n<+> diffusion layer 5 serving as the source region is provided on the surface between the grooves while a p<+> diffusion layer 3 serving as the gate region is provided in the grooves. A floating gate 11 is arranged between the FET diffusion layer 5 of the Step Cut construction and the insulator 7 made of oxide film or the like to limit the horizontal length of the channel area whereby the current flowing over the surface is checked. The gate 11 separated from the diffusion layer 3 prevents any increase in the capacity due to the larger area of the diffusion layer 3 serving as the gate region.
