摘要:
A thyristor has a pnpn four layer structure having a positive bevel in an anode side and a negative bevel in a cathode side. A ramp of a distribution of impurity concentrations in an anode-emitter layer near an anode-emitter junction is greater than a ramp of a distribution of impurity concentrations in a cathode-base layer near a central junction so as to improve the trade-off relation between the forward voltage drop and the withstand voltage.
