Abstract:
1. A plating method, comprising: holding a plating liquid in a plating bath; holding a substrate such that the substrate is inclined relative to a horizontal plane; holding an anode such that the anode is inclined relative to the horizontal plane so as to be in parallel to the substrate which is inclined relative to the horizontal plane; lowering the substrate relative to a surface of the plating liquid held in the plating bath while rotating the substrate to bring the surface of the substrate into contact with the surface of the plating liquid while supplying a plating electric current; plating the substrate to fill contact holes and trenches of the substrate with copper; stopping the supply of the plating electric current; lowering a liquid level of the plating liquid so as to expose the substrate above the surface of the plating liquid; rotating the substrate at a high speed, and then stopping the rotation of the substrate.
