Abstract: There is described an integrated circuit with junction insulation on a substrate (10) of semiconductor material comprising active regions (11, 11', 11'') of a first type of conductivity (n), insulation regions (30-33) which separate the junction-forming active regions from one another and from the substrate and means of electrical contact for reverse-biasing the junctions. In order to obtain highly efficient insulation, at least one (11) of the active regions is separated from the active regions adjacent to it (11') and from the substrate (10) by insulation regions (30-33) which form an inner insulation shell, consisting of regions (30, 31) of conductivity of a second type (p), opposite to the first type, which contains the active region (11) and an outer insulation shell, consisting of regions (32, 33) of the first type of conductivity (n) which contains the inner insulation shell.
