PROCESS-METROLOGY REPRODUCIBILITY BANDS FOR LITHOGRAPHIC PHOTOMASKS

A photomask lithography simulation model is created for making a semiconductor chip. Poor metrology is filtered and removed from a contour-specific metrology dataset to improve performance of the photomask. Filtering is performed by the application of a weighting scheme.
