Abstract
A silicon on insulator of integrated circuit comprising a plurality of components typically adopted for high voltage application having a semiconductor substrate of a first conductivity type, an insulating layer provided on the substrate, a semiconductor layer provided on the insulating layer, a number of laterally separated circuit elements forming parts of a number of subcircuits provided in the semiconductor layer, a diffusion layer of a second conductivity type opposite to that of the first conductivity type provided in the substrate and laterally separated from all the other circuit elements and means for holding the diffusion layer at a voltage at least equal to that of the highest potential of any of the subcircuits present in the integrated device.
