    摘要: A composite electrolytic processing method makes it possible to remove a conductive film without leaving it in an electrically-insulated state on an underlying barrier film, thereby exposing the barrier film. The electrochemical mechanical polishing method includes: applying a voltage between a first electrode connected to one pole of a power source and a second electrode, connected to the other pole of the power source, for feeding electricity to a conductive film of a polishing object; filling an electrolytic liquid into a space between the first electrode and the conductive film of the polishing object; and pressing and rubbing the conductive film against a polishing surface of a polishing pad to polish the conductive film in such a manner that a barrier film underlying the conductive film becomes gradually exposed from the center toward the periphery of the polishing object.

    摘要: An electrochemical mechanical polishing apparatus is for use in polishing of a conductive material (e.g., metal) on a surface of a substrate by combination of electrochemical action and mechanical action. This apparatus includes a polishing table having divided electrodes and adapted to hold a polishing pad having a polishing surface, a polishing head adapted to hold a workpiece having a conductive film and to press the workpiece against the polishing surface, a second electrode for supplying an electric current to the conductive film, an electrolytic-solution supply section for supplying an electrolytic solution to the polishing surface, a detecting section adapted to detect a signal corresponding to a thickness of the conductive film, a variable resistance unit having the same number of variable resistors as the number of divided electrodes, a moving mechanism for providing relative movement between the workpiece and the polishing surface, and a control section adapted to control each of the variable resistors based on the signal from the detecting section.

    摘要: An electrolytic liquid is used for electrolytic polishing which can provide a processed surface having high flattening characteristics with a low voltage applied while ensuring a higher processing rate for an conductive material, and can remove an unnecessary conductive material and expose a barrier film without causing dishing, erosion, or etching at the interface between the barrier film and a metal (conductive material). The electrolytic liquid for use in electrolytic polishing of a surface conductive material of a workpiece comprises an aqueous solution containing at least one organic acid or its salt, at least one strong acid having a sulfonic acid group, a corrosion inhibitor and a water-soluble polymeric compound.
