Patent ID: 8216503

Claim:
A method for manufacturing a printed circuit board, the method comprising the steps of: preparing a mold having a surface comprising a relievo pattern, the relievo pattern having a size of 0.1 to 50 μm; coating a polymerizing oxidant solution onto the mold surface comprising the relievo pattern; pressing the mold surface comprising the polymerizing oxidant solution coating into a semi-cured resin layer; separating the mold from the resin layer to form the relievo pattern in the resin layer, the resulting patterned layer having polymerizing oxidant solution from the mold surface adsorbed thereon; performing surface treatment on portions of the upper surface of the resin layer excluding the inside of the pattern formed therein to remove the polymerizing oxidant from the non-excluded portions; selectively filling the monomer of a conductive polymer over the remaining polymerizing oxidant inside the pattern formed in the resin layer; and polymerizing the selectively filled monomer to form a non-metallic conductive polymer fine wiring having a size corresponding to that of the relievo pattern formed on the mold, wherein the conductive polymer directly contacts the semi-cured resin, and wherein the surface treatment includes cleaning the upper surface of the resin layer with a polar solvent to remove the polymerizing oxidant or polishing the upper surface of the resin layer to remove the polymerizing oxidant.
