Abstract
The present invention relates to a process for forming a near-planar or planar layer of a conducting material, such as copper, on a surface of a workpiece using an ECMPR technique. The process preferably uses at least two separate plating solution chemistries to form a near-planar or planar copper layer on a semiconductor substrate that has features or cavities on its surface.
