Abstract
PURPOSE: To improve sensibility as well as dv/dt quantitative stability by making the gate electrode area larger against the cathode area, when forming a cathode of control rectifying element and a gate electrode.
CONSTITUTION: A p-type emitter layer 2 is formed on the back of an n-type semiconductor base plate 1, which is to form the base, and on the surface a p-type base layer 3 is provided. Next, inside the layer 3 an n-type emitter region 4 is diffusedly formed, on the back of the layer 2 an anode 5, on the surface of the region 4 a cathode 6, further on the surface of the layer 3 a gate electrode 7 are respectively fixed to constitute a thyristor. In said constitution, for enlarging dv/dt quantitative stability a short emitter constitution biassing displacement current toward the electrode 6 may be introduced. However, inspite of increased quantitative stability the sensibility decreases. Consequently the region 4 locating under the electrode 6 is divided in a plural number to make the area of the electrode effectively smaller against the area of the electrode 7 in order to improve both of sensibility and quantitative stability.
