发明名称 Copper metal precursor
摘要 A method for chemical vapor deposition of copper metal thin film on a substrate includes heating a substrate onto which the copper metal thin film is to be deposited in a chemical vapor deposition chamber; vaporizing a precursor containing the copper metal, wherein the precursor is a compound of (alpha-methylstyrene)Cu(I)(hfac), where hfac is hexafluoroacetylacetonate, and (hfac)Cu(I)L, where L is an alkene; introducing the vaporized precursor into the chemical vapor deposition chamber adjacent the heated substrate; and condensing the vaporized precursor onto the substrate thereby depositing copper metal onto the substrate. A copper metal precursor for use in the chemical vapor deposition of a copper metal thin film is a compound of (alpha-methylstyrene)Cu(I)(hfac), where hfac is hexafluoroacetylacetonate, and (hfac)Cu(I)L, where L is an alkene taken from the group of alkenes consisting of 1-pentene, 1-hexene and trimethylvinylsilane.
