Semiconductor component with first conductivity semiconductor substrate

摘要

On the semiconductor substrate (1) is formed a first semiconductor layer (3), in which is formed a second diffusion layer (4) of second conductivity, coupled to the first diffusion layer (2). The first semiconductor layer carries a second semiconductor layer (20). The second semiconductor layer is insulated from the substrate by the two diffusion layers. The first semiconductor and second diffusion layers are laminates of several layers, with the second laminate of second conductivity with its layer formed in each layer of the first layer laminate.
