A solvent composition useful for liquid delivery chemical vapor deposition of organometallic precursors such as β-diketonate metal precursors. The solvent composition comprises a mixture of solvent species A, B and C in the proportion A:B:C wherein A is from about 3 to about 7 parts by volume, B is from about 2 to about 6 parts by volume, and C is from 0 to about 3 parts by volume, wherein A is a C 6 -C 8 alkane, B is a C 8 -C 12 alkane, and C is a glyme-based solvent (glyme, diglyme, tetraglyme, etc.) or a polyamine. The particular solvent composition including octane, decane and polyamine in an approximate 5:4:1 weight ratio is particularly usefully employed in the formation of SrBi 2 Ta 2 O 9 films. |
