| 摘要 |
In the field of semiconductor production using shaped charged particle beam lithography, a method and system for fracturing or mask data preparation or proximity effect correction is disclosed, wherein a plurality of circular or nearly-circular shaped beam shots can form a non-circular pattern on a surface. Methods for manufacturing a reticle and for manufacturing a substrate such as a silicon wafer by forming non-circular patterns on a surface using a plurality of circular or nearly-circular shaped beam shots is also disclosed.
