摘要: Embodiments of the invention provide a method for conditioning contacts of an electrochemical metal plating system. The method includes deplating the contacts by supplying a reversed biased energy and monitoring electrical measurements of the plating system in real-time such that the endpoint of a deplating process can be determined. In different embodiments, the method includes the use of a constant current or voltage, variable current or voltage, or combinations thereof for conditioning the contacts.
