Abstract:
1. A copper film-forming composition comprising, as essential components, 0.01 to 3.0 mol/kg of copper formate or a hydrate thereof, 0.01 to 3.0 mol/kg of copper acetate or a hydrate thereof, at least one diol compound selected from the group consisting of diol compounds represented by the below-described formula (1) and diol compounds represented by the below-described formula (1′), a piperidine compound represented by the below-described formula (2), and an organic solvent with the copper formate or the hydrate thereof, the copper acetate or the hydrate thereof, the at least one diol compound and the piperidine compound dissolved therein, wherein, when a content of the copper formate or the hydrate thereof is assumed to be 1 mol/kg, the diol compound is contained in a range of 0.1 to 6.0 mol/kg and the piperidine compound is contained in a range of 0.1 to 6.0 mol/kg: wherein X denotes a hydrogen atom, methyl group, ethyl group or 3-aminopropyl group, and R 1 and R 2 each independently indicate a hydrogen atom or an alkyl group having 1 to 4 carbon atoms or may be fused together to form a 5-membered ring or 6-membered ring in combination with the adjacent nitrogen atom, and wherein R represents a methyl group or ethyl group, and m stands for 0 or 1.
