  • Patent number: 6736928
    Abstract: An exposure apparatus for sequentially performing exposure of device patterns provided in a pattern effective area of a photo-mask (10) on to shot areas of a wafer (20), to provide excellent throughput performance, includes an illumination unit (115) for collectively illuminating the entire pattern effective area of the photo-mask contained within the illumination range with exposure light, a mask stage (114) that moves the photo-mask for the illumination range in the mask scanning direction, and a wafer stage (111) that moves the wafer for the projection range in which the pattern effective area of the photo-mask is projected in the wafer scanning direction.

  • Patent number: 6670985
    Abstract: A PC card camera has a structure in which a universal joint to which a video camera is attached is mounted on a PC card body. The video camera comprises an optical lens unit and a solid-state area sensor of the photoelectric transducer type. The universal joint holds the video camera in such a manner that the angular position thereof can be adjusted freely with respect to the PC card. The PC card body is provided with a guide for guiding the card into a slot provided in a personal computer, a connector for connecting the PC card to the personal computer, and a cut-out which prevents the PC card from being inserted incorrectly. With the PC card connected to the personal computer, the angular position of the video camera can be adjusted via the universal joint.

  • Patent number: 6493600
    Abstract: A semiconductor manufacturing apparatus reduces limitation on operation position due to the layout of a factory, and enables an operator to check data in a working position upon maintenance of the apparatus, thus realizing efficient operation. A console having a display unit to display wafer information, recipe information, apparatus status and the like, and an input unit to input data and information, is removably fixed in any of a plurality of attachment positions provided on the semiconductor manufacturing apparatus main body, via a console attachment member. The height of the display unit and that of the input unit can be adjusted by height adjustment means having band members and fixing members.
