Abstract

Abstract PURPOSE: To prevent the deterioration of characteristics by a method wherein an electrode metal layer to be connected to an emitter region is arranged at the both side of end portions of emitter drawing electrodes. CONSTITUTION: The electrode metal layer is arranged at the both side of emitter drawing electrodes, connecting windows to the emitter region, 30-a, 30-b, 30-c, and 30-d are arranged separately at the four corners in the emitter region 13. Since the connecting windows to the emitter region 30-a, 30-b, 30-c and 30-d are separately arranged at the four corners in the emitter region, each connecting windows are located at approximately an equal distance from the edges of longirudinal and lateral direction. Therefore, the resistance between each edge in the emitter region 13 and each connecting window can be respectively made approximately equal to the resistance of little value.
