Abstract
PURPOSE:To make it possible to control turn-on time by constituting the N<+> emitter layer on the cathode side by thick and thin portions and forming an N<+> layer in the P layer on the anode side. CONSTITUTION:P type anode and base regions 3 and 2 are formed on both main surface sides on an N type substrate 1, and an N<+> emitter layer consisting of the thick and thin portions 4 and 8 is formed in said region 2. On the other hand, an N<+> layer 9 is formed in the region 3. Thus providing the thin portion 8 in the layer 4 permits the lateral spreading speed of current at this portion to be decreased. Moreover, by the presence of the partial layer 9 provided in the layer 3, the injection of holes from the layer 9 is locally restricted, a cross-current thyristor is formed when turning on, and the substantial spreading speed can be controlled. Thus, by properly arranging the thin emitter layer and the N<+> layer portion on the anode side and varying their widths in the current spreading direction, turn-on time can be controlled.
