摘要:
A thyristor device is provided with a shorted emitter structure in which the shorts are circularly formed zones of the base zone which extend through the emitter zone into electrical contact with the emitter electrode. Each of these zones is circular in cross-section and of a diameter which is less than 20.mu.m. These zones have a spacing from each other from center to center which is such that the ratio of this spacing to the diameter of a circular area is greater than 3.
