Abstract: The invention provides for the acceleration of a source mask optimization process. In some implementations, a layout design is analyzed by a pattern matching process, wherein sections of the layout design having similar patterns are identified and consolidated into pattern groups. Subsequently, sections of the layout design corresponding to the pattern groups may be analyzed to determine their compatibility with the optical lithographic process, and the compatibility of these sections may be classified based upon a “cost function.” With further implementations, the analyzed sections may be classified as printable or difficult to print, depending upon the particular lithographic system. The compatibility of various sections of a layout design may then be utilized to optimize the layout design during a lithographic friendly design process. For example, during the design phase, sections categorized as difficult to print may be flagged for further optimization, processing, or redesign.

Abstract: Aspects of the invention relate to pattern matching of layout design data. Layout design data is searched to identify configurations of geometric elements that match a reference pattern based on an anchor edge in the reference pattern. An edge in a search window area matching the anchor edge may first be selected as anchor matching edge. A search portion of the reference pattern is then compared with the region of the search window area corresponding to the selected anchor matching edge.

Abstract: A beam directing apparatus comprises a beam translator and a beam director. The beam translator is adapted to receive a beam at an input aperture and to output the beam at an output aperture, with the beam at the output aperture being parallel to the beam at the input aperture. The beam translator is further adapted to be capable of spatially translating the beam at the output aperture relative to the optical axis of the beam at the input aperture. The beam director includes at least one beam directing stage having a rotatable prism which is optically coupled to the output aperture.
