Abstract:
A method of forming a metal-containing film on a substrate, comprising the steps of:providing a metal source reagent composition comprising at least one metalorganic complex whose metal constituent is a metal component of the metal-containing film, and a solvent or suspending agent;volatilizing the metal source reagent composition to yield a metal source vapor;contacting the metal source vapor with a substrate under chemical vapor deposition conditions to deposit the metal-containing film on the substrate, wherein said metal source reagent composition comprises a metalorganic complex of the formula:MA.sub.y Xwherein:M is a y-valent metal;A is a monodentate or multidentate organic ligand coordinated to M which allows complexing of MA.sub.y with X;y is an integer having a value of 2, 3 or 4;each of the A ligands may be the same or different; andX is a mono dentate or multidentate ligand coordinated to M and containing one or more atoms independently selected from the group consisting of atoms of the elements C, N, H, S, O and F.
