  • Publication number: 20240176227
    Abstract: A photomask fabrication method comprising performing an optical proximity correction (OPC) on a design pattern to generate a correction pattern, and manufacturing the photomask having the correction pattern. The step of performing the OPC includes dividing the design pattern into a plurality of segments, producing a hash value for each of the plurality of segments, and generating the correction pattern by applying a first correction bias to ones of the plurality of segments having a same hash value, wherein at least two of the plurality of segments have the same hash value. The step of producing the hash value includes generating a key segment in a target segment, creating a query region around the key segment, and producing the hash value for the target segment based on a pattern image in the query region.
