Abstract:
A gate turn-off thyristor (GTO), comprising:a) in a semiconductor body, an npnp four-layer structure having cathode emitter regions, a p-type base, an e-type base and a homogeneous anode emitter;b) a stop layer, which is more heavily doped than the n-type base and is arranged between the n type base and the anode emitter;c) a bevelled edge termination region, which has no cathode emitter regions;d) a cathode, which makes contact with the cathode emitter regions, an anode, which makes contact with the anode emitter, and a gate which makes contact with the p-type base;whereine) a means which connects the stop layer to the anode emitter and which short-circuits the stop layer with the anode is provided in the edge termination region.
