  • Publication number: 20110092142
    Abstract: Retaining rings are presented with specially designed inserts that increase rigidity and improve heat dissipation. Inserts that are more rigid, and that have better ability to conduct heat, are inserted into pockets positioned along the outer portion of the rings. The pockets do not compromise the upper, lower or inner portion of the rings. Because the inserts are more rigid than the material used in the body of the ring, they absorb the deforming forces resulting from fastening the ring to the carrier head. Because they are better conductors than the material used in the body of the ring, the ring is better able to dissipate heat generated during polishing. Moreover, because the inserts are positioned in the outer portion of the ring, the inserts are not exposed to the polishing surface during polishing and therefore are less likely to react undesirably with the chemicals used during polishing.

    Abstract: A gas turbine component blank is shaped by clamping the gas turbine component blank into a fixture that accurately positions the gas turbine component blank in three dimensions. The positioning is accomplished against stops accurately machined into a base of the fixture, by first supporting the gas turbine component blank on one set of stops that prevents movement in the direction perpendicular to a plane of the base, and then operating a movable clamp to force the gas turbine component blank against other sets of stops that limit the movement of the gas turbine component blank in directions lying in the base plane. The clamp has a compound movement that simultaneously forces the gas turbine component blank against stops that prevent movement in orthogonal directions lying in the base plane. The gas turbine component blank is thereafter shaped, preferably by grinding the sides of the root precursor of the gas turbine component blank.

  • Patent number: 6764392
    Abstract: A polishing method and polishing apparatus capable of improving the flatness of a wafer are provided. When a wafer is adhered to a wafer holding plate for polishing a surface to be polished of the wafer by pressing and rubbing the surface to be polished against a polishing pad on a polishing turn table, the wafer is held by vacuum-chucking the surface to be polished of the wafer such that a surface to be adhered of the wafer forms a convex surface in a vicinity including an arbitrary point in the surface to be adhered within a region surrounding a center of the surface to be adhered of the wafer, and the region being at least not less than 50% of an entire adhesion area; and the wafer is adhered to the wafer holding plate from a central portion of the surface to be adhered of the wafer.

  • Patent number: 6479386
    Abstract: A process for forming a semiconductor wafer which is single side polished improves nanotopology and flatness of the polished wafer. The process reduces the effect of back side surface features, such as edge ring phenomena and back side laser marks, on nanotopology, thereby improving oxide layer uniformity for chemical/mechanical planarization (CMP) processing, and flatness on the polished front side of the wafer after polishing. The wafer is mounted on a polishing block by wax. The edge ring causes certain deformation and stress in the wafer upon mounting, which is held by the wax. After mounting, the wax is heated to allow the wafer to relax, removing the stress, without degrading the bond of the wafer to the polishing block. The wafer is polished and removed from the polishing blocks. The polished surface substantially retains its shape after being de-mounted from the block.
