In an oxide isolated semiconductor structure having an epitaxial layer formed on a monocrystalline substrate, a buried, laterally extending, PN junction in said structure, and oxidized isolation regions extending through said epitaxial layer to said PN junction, thereby to form a plurality of electrically isolated pockets of semiconductor material, a dopant is located in those regions of the semiconductor material directly adjacent the oxidized isolation regions. This dopant is often referred to as the field predeposition.
