    摘要: A polishing method can safely detach and lift up a workpiece from a polishing surface without carrying out the operation of making the workpiece overhang the polishing surface. The polishing method includes carrying out processing of a surface to be polished of a workpiece by supplying a liquid to a polishing surface while pressing the surface to be polished of the workpiece held by a holding device against the polishing surface and moving the workpiece and the polishing surface relative to each other, attracting the workpiece after the processing to the holding device while supplying the liquid to the polishing surface at a decreased flow rate, thereby detaching the workpiece from the polishing surface, and lifting up the holding device together with the workpiece on confirmation of detachment of the workpiece from the polishing surface and attachment of the workpiece to the holding device.

    摘要: A polishing apparatus is used for polishing a substrate such as a semiconductor wafer to a flat mirror finish. The polishing apparatus includes a polishing table having a polishing surface, a polishing head having at least one elastic membrane configured to form a plurality of pressure chambers for being supplied with a pressurized fluid, and a controller configured to control supply of the pressurized fluid to the pressure chambers. The controller controls supply of the pressurized fluid so that the pressurized fluid is supplied first to the pressure chamber located at a central portion of the substrate when the substrate is brought into contact with the polishing surface, and then the pressurized fluid is supplied to the pressure chamber located at a radially outer side of the pressure chamber located at the central portion of the substrate.

    摘要: A substrate holding apparatus has a substrate holder body with a substrate holding side facing a polishing surface and holding a substrate on the substrate holding side and a retainer ring fixedly secured to the substrate holder body. The retainer ring is arranged to surround an outer periphery of the substrate held by the substrate holder body so that the retainer ring engages with the polishing surface radially outside the substrate as the polishing of the substrate is effected. The substrate holder body is provided with a membrane having inside and outside surfaces. The inside surface cooperates with a surface of the substrate holder body to define a fluid pressure chamber to which a fluid pressure is applied. The outer surface engages with the substrate held by the substrate holder body.

    摘要: A polishing apparatus includes a polishing object holding mechanism for holding an object to be polished, and a table having a polishing surface. The polishing object held by the polishing object holding mechanism is pressed against the polishing surface of the table and polished by relative movement between the polishing object held by the holding mechanism and the polishing surface of the table. An elastic sheet 11 is stretched over the upper surface of the table, and a polishing pad 16 having a polishing surface on the upper side thereof is replaceably stretched over the elastic sheet 11. Thus, the function performed by an underlayer pad member of a double-layer polishing pad that has heretofore frequently been used in a chemical/mechanical polishing (CMP) apparatus is imparted to the table of the chemical/mechanical polishing (CMP) apparatus, thereby achieving cost reduction of chemical/mechanical polishing (CMP) process and stabilizing process performance such as polishing rate uniformity within a substrate surface to be polished.

    摘要: A polishing apparatus for polishing a workpiece such as a semiconductor wafer has a turntable with an abrasive cloth mounted on an upper surface thereof, and a top ring for holding a workpiece and pressing the workpiece against the abrasive cloth under a first pressing force to polish the workpiece. A guide ring is vertically movably disposed around the top ring, and pressed against the abrasive cloth under a variable second pressing force. The first and second pressing forces are variable independently of each other, and the second pressing force is determined based on the first pressing force.
