Abstract: PURPOSE:To simplify the whole process, and make the junction depth of a source.drain region sufficiently shallow, by forming simultaneously the emitter region of a bipolar transistor and the source.drain region of a MOS transistor by solid-phase diffusion from a polycrystalline silicon film. CONSTITUTION:After a polycrystalline silicon film is formed on the whole surface, and N-type impurity is ion-implanted therein, the emitter electrode 21 and the collector electrode 22 of a bipolar transistor and the source electrode 41 and the drain electrode 42 of a MOS transistor are formed by patterning of the polycrystalline silicon film. An emitter region 23, an aperture 24 to lead out a second collector, and a source.drain region 27, 28 are formed by diffusion from the left polycrystalline silicon films 21, 22, 41, 42.
