Abstract
A method of forming a thin film of BaSrTiO.sub.3 on a substrate in a chemical vapor deposition zone, with transport of a metal precursor composition for the metal-containing film to the chemical vapor deposition zone via a liquid delivery apparatus including a vaporizer. A liquid precursor material is supplied to the liquid delivery apparatus for vaporization thereof to yield the vapor-phase metal precursor composition. The vapor-phase metal precursor composition is flowed to the chemical vapor deposition zone for deposition of metal on the substrate to form the metal-containing film. The liquid precursor material includes a metalorganic polyamine complex, the use of which permits the achievement of sustained operation of the liquid delivery chemical vapor deposition process between maintenance events, due to the low decomposition levels achieved in the vaporization of the polyamine-complexed precursor.
