Patent ID: 8034403

Claim:
A copper distributing wire-forming method comprising the steps of forming a primary coat which consists of a vanadium- or titanium-containing film on a subject on which a film is to be formed, the film carrying holes and/or grooves formed thereon in advance, according to a CVD technique while using a raw gas consisting of a tetravalent amide vanadium-containing organometal compound or a tetravalent amide titanium-containing organometal compound as well as a reducing gas; and then forming a copper-containing film thereon by a CVD technique to thus fill the holes and/or grooves with the copper-containing film, wherein the copper-containing film is formed, on the subject on which a film is to be formed, according to the CVD technique while using a gas consisting of a copper complex represented by a following general formula (I-a), wherein in the general formula (I-a), X, Y and Z are the same as those defined below in connection with a following general formula (I-a)′, wherein formula (I-a) possesses, as a ligand, β-diketonate group represented by the general formula (I-a)′ in which Z represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; and X and Y, which may be the same or different from one another, each represent a linear or branched alkyl group having 1 to 8 carbon atoms or a C 1-8 alkyl group in which at most 9 hydrogen atoms thereof may be substituted with fluorine atoms:
