    摘要: In some embodiments, a method of controlling a width of an edge exclusion zone of a substrate is provided. The method includes determining a range of angles over which to rotate a polishing head; rotating the polishing head over the determined range of angles to achieve a preset width for an edge exclusion zone of the substrate; and polishing an edge of the substrate with the polishing head. Numerous other aspects are provided.

    摘要: Embodiments of the invention generally provide a method for electrochemically removing material from a substrate. In one embodiment, a method for electrochemically processing a substrate includes determining a process target for a substrate; electrochemically processing the substrate; determining a deviation between expected and actual process indicators while processing, and changing at least one process variable during processing in response to the variation.
