Abstract:
1. A method of forming a metal pattern, in which the metal pattern is formed by forming a plurality of metal cores by: performing sensitization treatment of a surface of a substrate with a copper compound, activating the sensitized surface of the substrate by activation treatment of the substrate, and forming a plated layer on the activated surface of the substrate, and wherein the method comprises: forming a conductive patterned film on a surface of an insulated substrate; performing sensitization treatment on the conductive pattern film by immersing the conductive pattern film into a sensitization solution including the copper compound to form a sensitized pattern film; activating the sensitized substrate by immersing the sensitized pattern film into an activation solution containing palladium, a palladium alloy, or palladium chloride to form an patterned activated multi-layered catalyst film comprising a plurality of catalyst metal cores thereon; and forming one or more plated layers on the surface of the patterned activated multi-layered catalyst film.
