LITHOGRAPHY SIMULATION AND OPTICAL PROXIMITY CORRECTION

Abstract:

Embodiments of the disclosure relate to lithography simulation and optical proximity correction. Field-guided post exposure bake processes have enabled improved lithography performance and various parameters of such processes are included in the optical proximity correction models generated in accordance with the embodiments described herein. An optical proximity correction model includes one or more parameters of anisotropic acid etching characteristics, ion generation and/or movement, electron movement, hole movement, and chemical reaction characteristics.
