Abstract

A monolithic assembly includes vertical power semiconductor components formed throughout the thickness of a low doped semiconductive wafer of a first conductivity type, whose bottom surface is uniformly coated with a metallization. At least some of these components, so-called autonomous components, are formed in insulated sections of the substrate, whose lateral insulation is provided by a diffused wall of the second conductivity type and whose bottom is insulated through a dielectric layer interposed between the bottom surface of the substrate and the metallization.
