http://www.chipmanufacturing.org/h-nd-409.html Webis that a pattern which is believed to be litho-unfriendly can be printed successfully depending on OPC algorithm and recipe. Considering OPC as an essential step, a litho-metric or fast lithography simulation [17,24] without OPC can burden a detailed router unnecessarily by blindly opti-mizing some easy-to-fix-by-OPC litho-hotspots.
