    摘要: A polishing apparatus can supply a polishing liquid uniformly and efficiently to a surface to be polished of a workpiece. The polishing apparatus includes a polishing table having a polishing surface, and a top ring for holding a semiconductor wafer and pressing the semiconductor wafer against the polishing surface. The polishing apparatus also includes a polishing liquid supply port for supplying a polishing liquid to the polishing surface, and a moving mechanism for moving the polishing liquid supply port to distribute the polishing liquid uniformly over an entire surface of the workpiece due to relative movement of the workpiece and the polishing surface.

    摘要: A method of polishing a wafer having a Ru film and a Ta film or TaN film beneath the Ru film is provided. This polishing method includes: polishing the Ru film by bringing the wafer into sliding contact with a polishing pad; measuring a thickness of the Ru film by a film thickness sensor while polishing the Ru film; calculating a derivative value of an output value of the film thickness sensor; detecting a predetermined point of change in the derivative value; and determining a removal point of the Ru film from a point of time when the point of change is detected.
