Optical Proximity Correction (OPC) Under Immersion …

WebDisclosed are a method of forming an optical proximity correction (OPC) model and/or a method of fabricating a semiconductor device using the same. The method of forming the OPC model may include obtaining a scanning electron microscope (SEM) image, which is an average image of a plurality of images taken using one or more scanning electron … WebIn printing random logic circuits down to 0.3 Ixm using i-line lithography, optical proximity correction is required to maintain across-the-chip linewidth uniformity. Using a rule-based approach with parametric anchoring, process characterization time is kept to a minimum. Corrections are more effective if post-OPC design grid sizes are kept ... flower garland shop near me
