Method for manufacturing wiring structure of wiring board

A method for manufacturing a wiring structure of a wiring board, comprising:

• providing a substrate comprising an insulation layer and a film disposed on the insulation layer, wherein the film completely covers the insulation layer;
• forming a barrier layer completely covering the film, wherein the barrier layer has an outer surface;
• forming an intaglio pattern partially exposing the insulation layer on the outer surface;
• forming an activated layer on the outer surface and in the intaglio pattern, wherein the activated layer completely covers the outer surface and all surfaces of the intaglio pattern;
• removing the activated layer on the outer surface, and remaining the activated layer in the intaglio pattern;
• forming a conductive material in the intaglio pattern by using a chemical deposition method after removing the activated layer on the outer surface, wherein the activated layer involves in chemical reactions of the chemical deposition method;
• and
• removing the barrier layer and the film after forming the conductive material,
• wherein the barrier layer is a metal layer, and a method for forming the barrier layer comprises depositing the metal layer on the film.
