    摘要: Polishing laps and apparatus incorporating such polishing laps for polishing workpieces such as semiconductor wafers are disclosed. The polishing laps are made from a cured mixture of an epoxy resin and a filler material, and preferably have at least a portion that is transparent to light. The polishing lap is preferably mounted on rigid polishing wheel or the like with or without an intervening layer such as an elastic layer. Polishing apparatus incorporating the polishing lap preferably include a light source for directing a beam of light toward the transparent portion of the polishing lap to enable the light beam to reflect from the working surface of the workpiece as the workpiece is being polished by the polishing lap. The apparatus also preferably includes a light detector for detecting light reflected from the surface of the workpiece. Such light can provide information, as on the status of the working surface as polishing progresses and can provide an indication of when polishing has reached a desired end point.

    摘要: After a hole is formed in a polishing pad, a transparent window plate is inserted into the hole. Here, a gap is left between the upper surface of the transparent window plate and the outermost surface constituting the working surface of the polishing pad. During polishing, the polishing head holding the wafer applies a load to the polishing pad by means of a load-applying mechanism, so that the polishing pad and transparent window plate are compressed. In this case, the system is arranged so that the gap remains constant, and so that a dimension equal to or greater than a standard value is maintained. Since the upper surface of the transparent window plate is recessed from the upper surface of the polishing pad, there is no scratching of the surface of the transparent window plate during dressing. Accordingly, the polishing pad has a long useful life.

    摘要: Apparatus and methods are disclosed for increasing the illuminance at a mask used for proximity-type microlithography and for achieving increases in throughput. A mask defining a pattern is illuminated by an illumination optical system. The pattern is transferred to a workpiece separated from the mask by a prescribed standoff. The mask and workpiece can be relatively moved in a scan direction. With respect to the illumination optical system, the workpiece-side numerical aperture in a first direction on the plane of the mask is different from the workpiece-side numerical aperture in a second direction, perpendicular to the first direction, on the plane of the mask. A reflective-type relay optical system can be included that comprises first and second spherical mirrors that do not produce chromatic aberrations.
