Plating method and apparatus

摘要

The present invention provides a plating method and apparatus, which is capable of introducing plating solution into the fine channels and holes formed in a substrate without needing to add a surface active agent to the plating solution, and capable of forming a high-quality plating film having no defects or omissions. The plating method for performing electrolytic or electroless plating of an object using a plating solution comprises: conducting a plating operation after or while deaerating dissolved gas in the plating solution; and/or conducting a preprocessing operation using a preprocessing solution after or while deaerating dissolved gas in the preprocessing solution and subsequently conducting the plating operation.
