  • Data generating method, data generating device, and program in an exposure system for irradiating multigradation-controllable spotlights
    Patent number: 7971159
    Abstract: To provide a data generating method, device, and program that can generate drawing data for drawing the entire general design graphic data with an accuracy of about 1 to 4 nm in a drawing method or a drawing system adapted to draw gradation-controllable spotlights in a two-dimensional array. The data generating method is a method for generating, in an exposure system having a function of irradiating multigradation-controllable spotlights in a two-dimensional array onto a photosensitive film on a substrate, gradation values of the spotlights based on design graphic data.
