    摘要: A method for electrochemical mechanical polishing (ECMP) is disclosed. The polishing rate and surface finish of the layer on the wafer are improved by controlling the surface speed of both the platen and head, controlling the current applied to the pad, and preselecting the density of the perforations on the fully conductive polishing pad. ECMP produces much higher removal rates, good surface finishes, and good planarization efficiency at a lower down force. Generally, increasing the surface speed of both the platen and the head will increase the surface smoothness. Also, increasing the current density on the wafer will increase the surface smoothness. There is virtually no difference in the smoothness of the wafer surface between the center, middle, and edge of the wafer. For copper, removal rates of 10,000 Å/min and greater can be achieved.

    摘要: Aspects of the present invention include a method and an apparatus that may be utilized to reduce dishing and improve cleaning efficiency of a material layer residue (e.g., copper residual) by varying a substrate potential in a substrate processing system. For example, by utilizing multiple polishing steps and applying different voltages (e.g., while a substrate is being in a polishing station), ECMP can be used to effectively reduce dishing and it can be used to enhance copper residual cleaning as well as minimizing a possibility of arcing, which can occur at the end of the polishing process, when a substrate is moved from a polishing station.
