  • Patent number: 6712674
    Abstract: A polishing apparatus includes a polishing pad rotated by a surface plate rotating shaft about a surface plate axis, a slurry conduit supplying slurry to an upper surface of the polishing pad, a substrate holding mechanism holding a substrate, a substrate rotating shaft rotating the substrate holding mechanism about a substrate axis, and a rotating mechanism rotating the substrate axis or the surface plate axis about an eccentric axis. The angular velocity of rotation about the eccentric axis is set larger than the angular velocity of rotation about the substrate axis or the surface plate axis. Thus, the effective contact area between a small area on the substrate and the polishing pad is increased, biased wear of abrasive grains on the polishing pad is prevented, clogging of the polishing pad is suppressed, and new abrasive grains and new chemicals can be supplied with high efficiency to each area of the substrate. Thus, the polishing rate is improved.

  • Patent number: 6702657
    Abstract: The frame of a polishing machine has a disc-shaped polishing table mounted thereon for rotation coaxially about a vertical axis, the table having thereon an upper, generally planar polishing surface for removably supporting thereon a plurality of annular workpiece carriers for rotation therewith and for rotation about their repsective axes relative to the table. The outer peripheral surface of each carrier is disposed to be engaged at angularly spaced points thereabout by a pair of rollers mounted on the frame for rotation about spaced, vertical axes. The output of a single AC electric motor is connected to the table to effect rotation thereof about its vertical axis, and to one roller of each pair thereof to drive the one roller about its axis. The one roller of each such pair thereof is in driving, rolling engagement with the carrier engaged thereby, while the other roller of such pair is rotated by the engaged carrier.

  • Patent number: 6645056
    Abstract: A method for producing, from a blank, restrictive tooling for use in an orbital polishing machine involves urging one of either the workpiece or the blank along a predetermined path against the other to physically impart a proportioned contour of the workpiece into the blank, thereby producing the restrictive tooling. Using this method, the same orbital polishing machine may be used to produce the restrictive tooling and to subsequently polish the workpiece.

  • Patent number: 6533648
    Abstract: A production type surface finishing apparatus for finishing the surfaces of workpieces such as cabinet doors and the like which include a plurality of relatively large, very lightweight finishing platens that are simultaneously movable in both a reciprocal and an orbital-like motion. The platen is moved in a reciprocal motion by a first motion-imparting mechanism and is simultaneously moved in a high-frequency, orbit-like motion by a second motion-imparting mechanism that includes shafts which are rotated at relatively high rates of speed. The shafts, and the motors which drive them, are mounted on platforms which are reciprocally movable relative to the main frame of the device. Connected to the rotating shafts by specially designed elastomeric sleeve-like members or yieldably deformable connector bands are specially configured, ring-like members. The rings are, in turn, connected to the platen assemblies by novel shaft and bearing assemblies.

  • Patent number: 6514129
    Abstract: Specific embodiments of the present invention provide a chemical-mechanical planarization apparatus for planarizing an object comprising a shaft having a shaft axis and being connected with a polishing head which is coupled to a polishing pad. The polishing pad has a smaller diameter than the object to be planarized. The shaft is rotatable to spin the polishing head and polishing pad around the shaft axis. An orbit housing has, spaced from an orbital axis, an eccentric hole through which the shaft is rotatably disposed. The orbit housing is rotatable to orbit the shaft, the polishing head, and the polishing pad around the orbital axis. In some embodiments, the object is rotated at an object rotational speed and the polishing pad is rotated around the orbital axis at an orbiting speed. A ratio of the greater of the object rotational speed and the orbiting speed to the lesser of the object rotational speed and the orbiting speed is a non-integer.
