Abstract
PURPOSE: To prevent the damage at symmetry properties even when the relative locations of n emitters mounted on two main surfaces slip or even when cutting position, shifts, by dividing an n emitter into more than one portions, and by uniformly distributing and arranging the emitters.
CONSTITUTION: An n emitter 7 is partitioned, and equally shared and disposed onto a main surface. Since it is necessary to moderate the rate of the total area of the n emitter 7 occupying in one device to the total area of a p base 8 exposed on the main surface and the n mitter is approximately half the p base generally, the dimensions of the divided emitters 7 and spacing are equalized or the emitters are made larger. Thus, the device is not formed in asymmetry in a shape as compared with the conventional devices, and an SSS device, a pnpn switch element, etc. can be manufactured.
