    摘要: A drum-type polishing apparatus for producing a flat mirror polish on an object such as a semiconductor wafer, is capable of three degrees of freedom of movement of a drum member with respect to the wafer. The relative movements can be made, successively or simultaneously, at right angles to an axis of the drum, parallel to the surface of the wafer, as well as at any desired angular orientations. Combined with a follower device to provide automatic compensation for unevenness in pressing pressure applied to the wafer during polishing, the polishing apparatus offers outstanding uniformity in polishing quality and high productivity, even for large diameter wafers, with a comparatively modest investment in both facility space and equipment cost.

    摘要: A polishing method and a compact apparatus for the method are presented for efficient production of a polished workpiece for manufacturing high technology devices. The polishing method comprises a first and second steps for polishing a work surface. In the first polishing step, the work surface is pressed against an abrading surface of a first polishing tool which is being rotated. In the second step, the work surface is pressed against a rubbing surface of a second polishing tool which is being moved in a planar translation motion relatively to the work surface.

    摘要: A workpiece such as a semiconductor wafer is polished by pressing the workpiece against a polishing surface under a predetermined pressure. A polished surface of the workpiece is processed by pressing the workpiece against a processing surface under a predetermined pressure while the processing surface makes circulatory translational motion along a predetermined path. The processing surface comprises a surface of a polishing cloth or a surface of an abrading plate, and the polished surface of the workpiece is further polished or cleaned.

    摘要: A method of producing a diagram for use in selecting wavelengths of light in optical polishing end point detection is provided. The method includes polishing a surface of a substrate having a film by a polishing pad; applying light to the surface of the substrate and receiving reflected light from the substrate during the polishing of the substrate; calculating relative reflectances of the reflected light at respective wavelengths; determining wavelengths of the reflected light which indicate a local maximum point and a local minimum point of the relative reflectances which vary with a polishing time; identifying a point of time when the wavelengths, indicating the local maximum point and the local minimum point, are determined; and plotting coordinates, specified by the wavelengths and the point of time corresponding to the wavelengths, onto a coordinate system having coordinate axes indicating wavelength of the light and polishing time.

    摘要: A polishing apparatus has a polishing section (302) configured to polish a substrate and a measurement section (307) configured to measure a thickness of a film formed on the substrate. The polishing apparatus also has an interface (310) configured to input a desired thickness of a film formed on a substrate to be polished and a storage device (308a) configured to store polishing rate data on at least one past substrate therein. The polishing apparatus includes an arithmetic unit (308b) operable to calculate a polishing rate and an optimal polishing time based on the polishing rate data and the desired thickness by using a weighted average method which weights the polishing rate data on a lately polished substrate.
