摘要: A drawing apparatus which can create an exposure pattern rapidly. The drawing apparatus has a raster conversion processing module for converting vector images as wiring patterns into bitmap image data, an image cache module for temporarily storing a predetermined-size cached image supplied from the raster conversion processing module, a first compression module for compressing the cached image stored in the image cache module, a second compression module for compressing the cached image stored in the image cache module in a compression ratio differing from that of the first compression module, a comparison module for comparing data sizes of compressed data generated by the first and second compression modules and selecting one having a smaller data size, a memory access module for writing the compressed data selected by the comparison module, into a storage module, and a cache region control module for controlling a compression status of the cached image.

摘要: The present invention provides a light exposure apparatus, and its method, comprising: an illumination optical system including: a light source array formed of a plural separate light sources arranged one-dimensionally or two-dimensionally; condensing optical system for condensing light emitted from each light source of the light source array; a light integrator for spatially decomposing the light condensed by the condensing optics, and thus generating a multitude of pseudo-secondary light sources; and a condenser lens for overlapping the light rays emitted from the multitude of pseudo-secondary light sources generated by the light integrator, and thus illuminating an illumination target region having a pattern to be exposed; and a projection optical system for projecting transmitted or reflected light onto an exposure target region of an exposure target object in order to expose the pattern to be exposed that is illuminated by the illumination optical system.
