Abstract:
A model-based tuning method for tuning a first lithography system utilizing a reference lithography system, each of which has tunable parameters for controlling imaging performance. The method includes the steps of defining a test pattern and an imaging model; imaging the test pattern utilizing the reference lithography system and measuring the imaging results; imaging the test pattern utilizing the first lithography system and measuring the imaging results; calibrating the imaging model utilizing the imaging results corresponding to the reference lithography system, where the calibrated imaging model has a first set of parameter values; tuning the calibrated imaging model utilizing the imaging results corresponding to the first lithography system, where the tuned calibrated model has a second set of parameter values; and adjusting the parameters of the first lithography system based on a difference between the first set of parameter values and the second set of parameter values.

Claim (Index 35):
A non-transitory computer readable medium comprising instructions, when executed by a hardware computer system, configured to cause at least:\n obtaining of measurement results from a substrate exposed using a lithography system that is set using reference values; obtaining of simulation results using a model of the lithography system and the reference values; and based at least on the simulation results and the measurement results, variance of a parameter of the lithography system that corresponds to the reference values such that a value of the varied parameter of the lithography system at least in part defines, as a best match or within an error criteria, a desired imaging condition of the lithography system.
