    摘要: On a surface of a substrate having a plateable material portion and a non-plateable material portion, a polymer compound, which selectively reacts with an OH end group of the non-plateable material portion, is supplied. By performing a catalyst imparting processing on the substrate on which the polymer compound is supplied, a catalyst is selectively imparted to the plateable material portion. Further, by performing a plating processing on the substrate, a plating layer is selectively formed on the plateable material portion. Before or after forming the plating layer, the polymer compound on the substrate is removed.
