    摘要: By forming a first copper layer on a substrate by using a complexing agent for copper ion, which has a low copper complex stability constant, a uniform second layer can be stably formed by a second complexing agent for a copper ion, which has a high copper complex stability constant, even if the substrate is composed of a material having a low catalytic activity, such as tungsten, or even if the catalytic activity of the substrate is uneven. A similar effect can also be obtained by adding a small amount of a complexing agent for a copper ion, having a low stability constant, to an electroless copper plating bath containing a complexing agent for a copper ion, having a low stability constant. In this case, an effect of preventing stopping of the reaction of the complexing agent of a copper ion, having a high stability constant, is attained. Most preferably, after formation of a uniform first copper layer by an electroless copper plating solution containing a complexing agent for a copper ion, having a low stability constant, a second copper layer is formed by an electroless copper plating solution containing a complexing agent for a copper ion, having a high stability constant and also in this case, a small amount of a complexing agent for a copper ion, having a low stability constant, is added.

    摘要: A practically fast electroless copper plating solution is provided by adding a specific monoamine as an accelerator. The accelerator should be a tertiary monoamine and cannot be a diamine, does not have a complexing ability for copper ion, and does not contain a ketone or carboxyl group or an unsaturated group. Specific examples of such monoamines include triethylamine, tripropylamine, tribenzylamine, N-methyl-piperidine, and tris (4-bromophenyl) amine, N-methylmorpholine.
