Abstract: An improvement in the method of ion implantation into a semiconductor substrate through a photoresist mask wherein the photoresist mask is subjected to an RF gas plasma oxidation prior to the ion implantation step for a period sufficient to reduce the thickness of the photoresist layer. The ion implantation is then carried out through the treated photoresist mask.

Abstract: An infrared sensitive photoconductive material is produced by growing a ternary compound of the formulation Hg(1-x) Cdx Te from a gaseous mixture of mercury, cadmium and tellurium onto a substrate which promotes polycrystalline growth and is chemically inert vis-a-vis the constituent gases. Suitable substrate materials are quartz, sapphire, and certain types of glass which are nonmeltable at growth temperatures of the ternary compound. The method preferably grows the polycrystalline material from a gaseous mixture of mercury, cadmium and tellurium heated to a temperature which inhibits binary combinations and then is rapidly cooled to supersaturation very close to the surface of a solid amorphous substrate material although crystalline substrates may be used provided the lattice structure in growth is incompatible with the lattice of the ternary compound.
