System and method for electroplating fine geometries

摘要

An electroplating system is described which provides for the formation of a conductive layer on a workpiece. The current used to electroplate the workpiece is controlled by a controller. The rotation of the workpiece within a solution containing conductive material is controlled by a rotation controller. The current level and/or rotation of the workpiece is controlled in such a way that the non-uniform growth of large grains within the conductive film is minimized.
