Claim:
1. A plating method of performing plating processes by supplying plating liquids onto a surface of a substrate by using a plating apparatus, wherein the plating apparatus comprises: a substrate rotating holder configured to hold and rotate the substrate; a plurality of plating liquid supply units configured to supply different kinds of plating liquids onto the surface of the substrate held by the substrate rotating holder; and a plating liquid drain unit disposed in a vicinity of the substrate rotating holder and configured to separate the plating liquids dispersed from the substrate depending on the kinds of the plating liquids and drain out the separated plating liquids through drain openings of a cup included in the plating liquid drain unit, and wherein the plating method comprises: performing a first plating process on the surface of the substrate by supplying a first plating liquid onto the surface of the substrate from one of the plating liquid supply units; after performing the first plating process, collecting the first plating liquid which has been used through a first drain opening of the cup; performing a second plating process on the surface of the substrate by supplying, from another one of the plating liquid supply units, a second plating liquid different from the first plating liquid supplied from the one plating liquid supply unit; and after performing the second plating process, collecting the second plating liquid which has been used through a second drain opening of the cup by vertically moving the cup, and wherein the substrate is continuously rotated during performing the first plating process and the second plating process.
