Abstract
PURPOSE: To increase the di/dt rating by providing the high resistance region to block the gate current detouring occurring in the currentpath withn the base layer between the gate electrode and its opposing emitter layer's edge.
CONSTITUTION: PN-junction J3 is caused with N-type emitter layer 5 and P-type base layer in order to form part of the thyristor of the PNPN-layer structure. Then the gate electrode is attached on the back of layer 6 with cathode electrode 2 attached on layer 5, and furthermore short emitter layer 9 is added to increase the dv/dt rating. In this constitution, gate electrode 3 and both-end part 61 of layer 6 are thinned to secure a high resistance there and in order to increase the di/dt rating without affecting the dv/dt rating. Thus, no concentration of the gate current occurs at that area due to part 61, and a wide region can be turned on along edge Q-R of layer 5. As a result, the di/dt rating can be increased
