SUMMARY
Electron Beam Lithography (EBL) has a resolution limit of sub-10 nanometers, which raises questions about the utility of drawing lines and dots in CAD files. Users often employ CAD software to create masks, saving them in DXF format before converting to GDS, where closed polylines are interpreted as part of the pattern. In specialized lithography software like L-Edit, lines and dots smaller than the minimum feature size serve primarily as drawing aids and should be removed prior to mask fabrication. Thus, while lines and dots can be useful for dose modulation and design clarity, they do not contribute to the final pattern if they fall below the resolution threshold.
