Abstract

PURPOSE:To obtain approximately twice the circumferential length of an emitter as well as to sharply reduce the base resistance for the subject transistor by a method wherein a concentric annular P type emitter is provided on the inner side of an annular collector and a P type collector is provided inside the P type emitter. CONSTITUTION:An N<+> base connection layer 6, the first P<+> type collector 3, an emitter 7 and the second collector 8 are provided in concentric annulation on the N epitaxial layer on the Si substrate 1, having an N<+> buried layer 5, as prescribed, an aperture is provided on an SiO2 film 9 and an Al electrode 10 is attached. The base resistance of the horizontal type transistor of this constitution can be reduced to the fullest extent by reducing its area to the minimum. Also, when the outside collector CA and the inside collector CB are used independently, the base current does not increase even when the CB is saturated.
