A multi-layer printed circuit board and a manufacturing method thereof are provided to reduce the amount of pollutants by reducing the amount of high cost catalyst required for a masking process. A multi-layer printed circuit board includes a substrate(100), an SAM(Self-Assembled Membrane)(103), a catalyst layer(109), a metal membrane, and a first circuit. At least one minute hole is formed on the substrate. The SAM is formed on at least one surface of the substrate. The catalyst layer is formed on a surface of the minute hole on the substrate. The metal membrane is formed on the surface of the minute hole, where the catalyst layer is formed. The first circuit is formed on the SAM. The SAM includes a layer, which is formed by cathode and anode electrolyte solution. |
