Abstract

A method and associated apparatus for electro-chemically depositing a metal film on a substrate having a metal seed layer. The apparatus comprises a substrate holder that holds the substrate. The electrolyte cell receives the substrate in a processing position. The actuator is connected to the substrate holder and adjustably positions the substrate relative to the electrolyte cell. The method involves electro-chemically depositing a metal film on a substrate having a metal seed layer comprising disposing the substrate in an electrolyte cell that is configured to receive the substrate. The method comprises adjustably positioning the substrate relative to the electrolyte cell.
