Abstract

PURPOSE:To prevent the stoppage of operation of subject device under high collector voltage by a method wherein a high concentration buried layer is arranged on the collector region surrounding an emitter region at the place directly below the section facing the outer base lead-out layer. CONSTITUTION:An epitaxial layer 3 on a P type Si substrate is separated into a frame-shaped by a P layer 2. An N<+> base electrode lead-out layer 3b is formed on the base layer 3 facing an emitter layer 5 outside P emitter layers 4 and 5 surrounding P collector layers 4 partially overlapping the separated region 3 with the P layer 2. However, an N<+> buried layer 10 is provided at the bottom section of the N base layer 3 located directly below the layer 4 facing the layer 3b. According to this constitution, a depletion layer does not spread out from the P type substrate 1 by the presence of the N buried layer, the pinch-off voltage of parasitic FET becomes much higher than the bias voltage between the base and collector in practically use for the element and the base electrode 3a and an emitter electrode 5a will not be disconnected. Through these procedures, the device without stoppage of operation can be obtained even when it is operated at a high collector voltage at a high collector voltage at a high gain.
