A workpiece surface processing apparatus capable of processing the surface of a workpiece without being limited as to the shape of the workpiece and further capable of measuring the state of polish of the workpiece with a high precision. The workpiece surface processing apparatus includes three platens 1-1 to 1-3 arranged substantially point symmetrically and being rotated in the same direction by motors 17 to 19, a carrier head 2 holding a wafer W and rotating in an opposite direction to the platens 1-1 to 1-3, a rocking mechanism 3 for making the wafer W rock in a diametrical direction of the platen 1-1 so that the entire surface of the wafer W is polished. A measuring device 4 continuously measures the state of polish of the entire surface of the wafer W. <IMAGE> |
