Patent ID: 7807223

Claim:
A method for depositing a ruthenium containing film into a reactor onto a substrate comprising the steps of: a) providing a substrate into the reactor, at reaction temperature; b) introducing at least one ruthenium containing precursor into the reactor, wherein the precursor comprises at least one precursor selected from the group consisting of: Ru(diketonate) 2 X 2 ; Ru(diketonate) 2 (amidinate) 2 ; their derivatives, and mixtures thereof; wherein: the diketonate group comprises at least one member selected from the group consisting of: acetylacetonate; hexafluoroacetylacetonate; tetrafluoroacetylacetonate; octafluorohexadionate; heptafluoro-dimethyloctanedionate; tetramethylheptdionate; and dimethylheptadionate; X comprises a 2-electron donor complex; and the amidinate comprises an amidinate group with the general formula: R 1 CNC(R′)NCR 2 wherein each radical R i (R 1 , R 2 , R′) is independently selected from the group consisting of: C1-C12 linear, branched, or cyclic alkyl groups; and a perfluorocarbon group of the general formula C x F (2x+1) , where x is less than 16; c) introducing into the reactor a gas mixture comprising hydrogen and/or oxygen; and d) reacting the ruthenium containing precursor and the gas mixture to deposit a ruthenium containing film onto the substrate.
