Abstract
Semiconductor integrated circuits comprising a dielectric isolation semiconductor chip having a plurality of monocrystalline semiconductor regions electrically separated by a polycrystalline semiconductor and dielectric insulation films, and circuit elements formed in the monocrystalline regions, wherein the polycrystalline substrate includes a high resistivity layer and a low resistivity layer, at least the high resistivity layer is adjacent to the monocrystalline region and the low resistivity region is coupled to a contact provided on a surface of the chip, whereby an electrostatic coupling between the circuit elements is shielded by the low resistivity layer to prevent cross-talks due to the electrostatic coupling. A method of manufacturing the same is also disclosed.
