Abstract

In a method for producing a plurality of integrated semiconductor devices e.g. vertical, planar transistors on a monocrystalline substrate (1) zones (3) strongly doped with a second type of conductivity which is opposite to that of the substrate are formed by diffusion and then there is grown uniformly over the face (2) of the substrate (1) an epitaxial layer (4,5) into which various doping agents are successively diffused with selective masking to form insulation columns (6), a base zone (7) and an emitter zone (8). This epitaxial growth is divided into two stages, the first of which is to form a first uniformly distributed layer (4) of the same type of conductivity as the substrate (1) and having a thickness which is limited such that in the finished structure the diffused zones (3) are not covered by this first epitaxial layer (4). The second of the stages is to form a second uniformly distributed epitaxial layer (5) of opposite conductivity to that of the substrate (1). <IMAGE>
