11 48,917 ABSTRACT OF THE DISCLOSURE The present invention comprises a thyristor formed by four successive adjoining regions, said regions comprising an emitter of a first type conductivity, a first base region of a second type conductivity, a second base region of the first type conductivity and a second emitter region of the second type conductivity, p-n junc- tion's between adjacent regions, characterized in that gate regions of the second type conductivity are provided at predetermined intervals on a boundary surface between said base region of the first type conductivity and said base region of the second type conductivity to protrude in the form of islands or a comb-like structure into said base region of the first type conductivity from said base region of the second type conductivity while high impurity concentration regions of the first type conductivity are provided only on portions not vertically opposing to said gate regions of the second type conductivity on a boundary surface between said base region of the first type conduc- tivity and said emitter region of the second type conduc- tivity or, a high impurity concentration region is pro- vided to be thicker on said portions than on the remaining portions.
