Optical proximity correction model
WebIn this thesis, we first look at the Optical Proximity Correction (OPC) problem and define the goals, constraints, and techniques available. Then, a practical and general OPC framework is built up using concepts from linear systems, control theory, and computational geometry. WebA technology of optical proximity correction and lithography mask, which is applied in optics, originals for photomechanical processing, photoplate making process of patterned surface, etc., can solve the problem of poor resolution of corrected graphics, achieve improved resolution, Avoid the effect of too small width and improve exposure conditions
