Abstract: PURPOSE:To improve the level of integration of a semiconductor device without deteriorating its function by bringing the active layers of an emitter and collector formed in a base layer into contact with an insulating section and completely insulating and separating a PNP junction transistor from the other part of a substrate. CONSTITUTION:The device has a buried insulating layer 102 formed in a semiconductor substrate 101 and element areas isolated and separated from the substrate 101 by means of the layer 102 and insulating sections 103. Horizontal PNP junction transistors are contained in the element areas and an emitter active layer 106 and collector active layer 107 formed in a base layer are brought into contact with an insulating section 112. Thus the horizontal PNP junction transistors are completely separated from the substrate 101.
