Patent ID: 8557339

Claim:
A process for the deposition of a ruthenium containing film on a substrate, comprising the steps of: a) providing at least one substrate into a reactor; b) introducing into the said reactor at least one organo-metallic compound of the formula (I): L-Ru—X (I) wherein: L is a non-aromatic cyclic unsaturated hydrocarbon ligand (L), having at least six cyclic carbon atoms, said cycle being unsubstituted or substituted by one or more substitution groups selected from linear or branched alkyl groups having from one to six carbon atoms unsubstituted or substituted by one or more radicals selected from fluoro, hydroxy or amino, linear or branched alkylamide groups having from one to six carbon atoms, linear or branched alkoxy groups having from one to six carbon atoms, linear or branched alkyl amidinates having from one to six carbon atoms, and X is either a non aromatic cyclic unsaturated hydrocarbon ligand identical or different from (L), having at least six cyclic carbon atoms said cycle being unsubstituted or substituted by one or more substitution groups selected from linear or branched alkyl groups having from one to six carbon atoms unsubstituted or substituted by one or more radicals selected from fluoro, hydroxy or amino, linear or branched alkylamide groups having from one to six carbon atoms, linear or branched alkoxy groups having from one to six carbon atoms, linear or branched alkyl amidinates having from one to six carbon atoms, or a cyclic or acyclic conjugated alkadienyl hydrocarbon ligand having from five to ten carbons atoms, said hydrocarbon ligand being unsubstituted or substituted by one or more substitution groups selected from linear or branched alkyl groups having from one to six carbon atoms unsubstituted or substituted by one or more radicals selected from fluoro, hydroxy or amino, linear or branched alkylamides group having from one to six carbon atoms, linear or branched alkoxy groups having from one to six carbon atoms, linear or branched alkyl amidinates having from one to six carbon atoms; c) decomposing or adsorbing on the substrate(s) said at least one organo-metallic compound into the said reactor set at a temperature equal or higher than 100° C.; and d) depositing said ruthenium containing film onto said at least one substrate.
