Abstract of the Disclosure

Electronic elements of an integrated circuit are combined within a unitary body but are isolated, at least from the substrate, by a layer of material whose resistivity is high, approaching intrinsic material. The high resistivity layer is followed by a subsequent layer or layers with diffused regions formed therein to complete the electronic elements.
