  • Patent number: 6556280
    Abstract: A lithographic tool system for generating an interferometric pattern of light using a plurality of exposure beams includes a processor coupled to a positioning device. The processor receives a selected period for the interferometric pattern of light, and generates an angular control signal and a translational control signal in response to the selected period. The positioning device translates an exposure beam in response to the translational control signal, and rotates the exposure beam in response to the angular control signal.
    Type: Grant

  • Patent number: 6522433
    Abstract: A method and apparatus for interference lithography utilize a fiber having a cladding region with axially formed holes surrounding a core region. The fiber emits an optical signal to perform interference lithography. A number of alternative variations in the size and arrangement of axially formed holes produces fibers having characteristics particularly adapted for receiving, communicating, and emitting optical signals for interference lithography.

  • Publication number: 20020149757
    Abstract: A polarization vector alignment technique for interference lithography generates a control signal indicating a difference in orientation between a polarization state of an emitted optical signal and a desired linear polarization vector. The technique adjusts the linear polarization vector to enhance the quality of the pattern produced for interference lithography.
