Abstract:
An interferometric microlithography system for producing a spatially non-periodic pattern comprising:a source of coherent electromagnetic radiation producing a plurality of coherent electromagnetic beams;a plurality of beam controllers, each of said beam controllers positioned to receive a respective one of said plurality of said coherent electromagnetic beams and direct said respective coherent electromagnetic beam into a region of overlap defined by an intersection of all of said plurality coherent electromagnetic beams; anda system controller in electrical communication with each of said plurality of said beam controllers,wherein each beam controller controls at least one of the phase, amplitude and polarization of a respective one of said plurality of coherent electromagnetic beams in response to control signals from said system controller, andwherein said spatially non-periodic pattern is formed within said region of overlap by the interference of said plurality of coherent electromagnetic beams in response to said control signals from said system controller.
