Abstract:
A method for forming an oxide film on a substrate comprising the steps of:(a) vaporizing an oxide precursor selected from the group consisting of aluminum (III) n-butoxide, yttrium isopropoxide, titanium-di-n-butoxide (bis-2, 4-pentanedionate), zirconium isopropoxide, tantalum (V) n-butoxide, niobium (V) n-butoxide and zinc n-butoxide;(b) dissociating the vaporized precursor at a temperature in the range of about 400.degree. C. to about 800.degree. C.; and(c) polymerizing the dissociated, vaporized precursor on the substrate at a temperature below about 300.degree. C.
