Web1 apr. 2011 · Optical aberrations are incorporated into the model by modeling their coefficients as independent, normally distributed random variables with zero mean and identical non-zero variance. To minimize the difference between actual and optimum images over a range of aberrations, the optimization function takes many of the differences into … WebGenerating legal and diverse layout patterns to establish large pattern libraries is fundamental for many lithography design applications. Existing pattern generation models typically regard the pattern generation problem as image generation of layout maps and learn to model the patterns via capturing pixel-level coherence, which is insufficient to …
