Patent number: 6458014Abstract: 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.Type: GrantFiled: May 2, 2001Date of Patent: October 1, 2002Assignee: Nikon CorporationInventors: Akira Ihsikawa, Tatsuya Senga, Akira Miyaji, Yoshijiro Ushio

Patent number: 5891806Abstract: 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.Type: GrantFiled: April 17, 1997Date of Patent: April 6, 1999Assignee: Nikon CorporationInventors: Masato Shibuya, Keiichiro Sakato, Akira Miyaji, Toshiyuki Namikawa, Takashi Mori

Patent number: 5559584Abstract: An exposure apparatus is for illuminating a pattern on a mask by an illumination optical system to transfer the pattern on the mask onto a photosensitive substrate set on a stage through a projection optical system. The exposure apparatus comprises a first supply device for supplying an inert gas toward the photosensitive substrate substantially in parallel with the optical axis of the projection optical system in a space open to communicate with the atmosphere between the projection optical system and the photosensitive substrate, and a second supply device for supplying the inert gas to the space in a direction intersecting with the optical axis of the projection optical system so as to establish an inert gas atmosphere in the space together with the first supply device. The transfer is conducted in the inert gas atmosphere.Type: GrantFiled: January 30, 1995Date of Patent: September 24, 1996Assignee: Nikon CorporationInventors: Akira Miyaji, Masatoshi Ikeda
