Abstract
A treated substrate produced by a process for treating a dielectric layer on a substrate, which comprises applying a sufficient amount of a liquid dielectric composition onto an upper surface of a semiconductor substrate to thereby form a dielectric layer on the upper surface of the substrate, the dielectric layer having a thickness of from about 2,000 to about 50,000 angstroms; heating a surface of the dielectric layer and exposing the dielectric layer to an electron beam radiation, in which the electron beam radiation is concentrated at a distance within about 1,000 angstroms from the surface of the dielectric layer, under vacuum conditions to remove substantially all moisture and/or contaminants from the surface of the dielectric layer at a depth of up to about 1,000 angstroms from the surface of the dielectric layer; and chemical vapor depositing a chemical vapor deposit material onto the surface of the treated dielectric layer while maintaining the vacuum conditions.
