Abstract
A method of surface treating a surface and semiconductor article is disclosed. A deposited surface layer on a substrate, such as a semiconductor surface, is treated and annealed within an alkyl environment of a chemical vapor deposition chamber to passivate the surface layer by bonding with the silicon and attaching alkyl terminating chemical species on the surface of the surface layer to aid in dehydroxylating the surface. The surface layer comprises a silicon-oxy-carbide surface layer having a carbon content ranging from about 5% to about 20% at the molecular level and a dielectric constant of about 2.5 to about 3.0.
