Abstract

PURPOSE:To improve the firing characteristic of a thyristor , by selectively shaving off the surface part of a substrate between a gate and cathode electrodes arranged at the center of the same surface of a semiconductor substrate. CONSTITUTION:The substrate 1 is equally divided into six regions A-F with cutting part Ce' respectively provided on the regions A, C and E. When firing the thyristor, the firing of the regions B, D and F easily fired parts accompanies the firing of the regions A, C and E not easily fired parts. Therefore, the current required to fire all of the parts is enough at half value thereof. Thus, firing characteristic can be controlled.
