Claim:
1. A plating method comprising: a first material plating process of forming a first material layer on a substrate by supplying a first plating liquid onto the substrate; a second material plating process of forming a second material layer on the first material layer, the second material layer being made of a different material from the first material layer; wherein the second material plating process comprises: an incubation process of forming a film on an entire region of the first material layer by supplying a second plating liquid onto the substrate while stopping the rotation of the substrate or rotating the substrate at a first rotational speed to reduce a movement of the second plating liquid; after the completion of the incubation process, a growing process of growing the film in the growing process such that the grown film thickness increases by 10 times or more by continuously supplying the second plating liquid onto the substrate while increasing the first rotational speed of the substrate to a second rotational speed that is greater than the first rotational speed to replace the second plating liquid in which a concentration of a reactive species is reduced in the growing process with a new second plating liquid.
