Web26 mrt. 2015 · These forms consistently show a 25-30% improvement in accuracy for the prediction of wafer results. Improvements in the prediction of resist toploss and scumming – as well as SRAF printing for both PTD and NTD cases – have been achieved over the past year. Faster models for 10nm lithography. Accuracy is not the only consideration. WebSRAF patterns themselves, the small SRAF patterns can transfer light to the positions of target patterns, and therefore SRAFs are able to improve the robustness of the target …
