  • Patent number: 7518732
    Abstract: Improved systems, apparatus, and methods for detecting positions of moving stages and a reference position of a beam column are provided. For some embodiments, independent discrete interferometers may be utilized for distance measurements in each axis, rather than a cumbersome monolithic multi-axis interferometer utilized in conventional systems.
    Type: Grant
    Filed: October 22, 2007
    Date of Patent: April 14, 2009
    Inventors: William A. Eckes, Jeffrey Sullivan, Kurt Werder

  • Patent number: 5644137
    Abstract: An electron beam apparatus is provided with a support mechanism upon which X and Y axis interferometers are mounted within a vacuum chamber. By employing a flat ring of a low coefficient of thermal expansion glass ceramic composition affixed beneath the chamber upper wall and to which the interferometers are mounted, the normal extremes of vacuum and heat as existing within the chamber are resisted to insure of a fixed horizontal alignment of the beams as projected by the interferometers during operation of the apparatus. Flexure mounts are included for the interferometer ring together with a magnetic shield disposed adjacent the ring undersurface. Stability of workpieces is further enhanced by the use of the same glass ceramic composition in the formation of the carrier and its reference plate of the apparatus.
