Abstract
PURPOSE: To reduce a power loss in a graft base region by wiring electrodes, formed in an emitter region and a bse region, in three imentions and by expanding an emitter electrode over the graft base region via an insulator layer.
CONSTITUTION: On N+-type semiconductor substrate 11, N-type layer 12 is grown, in which P-type base region 13 is formed by diffusion. In this region 13, several N-type emitter regions 14 are formed by diffusion and among them, P-type graft base regions 15a intruding into layer 12 are provided. Then, emitter electrode 17 and base electrode 19 are formed in regions 14 and regions 15a respectively in three dimentions. Namely, a metal electrode is bonded where electrodes 18 and 19 are formed, the entire surface is covered with insulator layer 19, and only layer 19 on electrode 17 is removed by photolithographing. On layer 19, independent eimitter electrode 20 meeting electrode 17 is formed expanding over electrode 19.
