Abstract:
A method for forming a Group II metal-containing film on a substrate, comprising the steps of:providing a liquid delivery apparatus including a vaporizer and a chemical vapor deposition zone; transporting a liquid precursor composition for said Group II metal-containing film to the vaporizer of the liquid delivery apparatus for vaporization of the precursor composition to yield a vapor-phase Group II metal precursor composition; and flowing the vapor-phase Group II metal precursor composition to the chemical vapor deposition zone for subsequent deposition of the Group II metal-containing film on the substrate therein, using a liquid precursor material that includes barium bis(2,2,6,6-tetramethyl-3,5-heptanedionate) imine adduct having a generally clear viscous oil form, and the Ortep diagram structure illustrated in FIG. 8 or 9 hereof.
