Abstract
A method for fabricating a wiring structure of a wiring board is provided. First, a substrate including an insulation layer and a film disposed on the insulation layer is provided. Next, an intaglio pattern exposing the insulation layer is formed on an outer surface of the film. The intaglio pattern is formed by removing a portion of the insulation layer and a portion of the film. Next, an activated layer is formed on the outer surface and in the intaglio pattern. The activated layer completely covers the outer surface and all surfaces of the intaglio pattern. Then, the film and the activated layer on the outer surface are removed, and the activated layer in the intaglio pattern is remained. After the film and the activated layer on the outer surface are removed, a conductive material is formed in the intaglio pattern by chemical deposition method.
