Claim 12:
13. A non-transitory computer readable medium comprising stored instructions, which when executed by a processor, cause the processor to perform operations comprising:
accessing a mask pattern for use in a lithography process that prints a pattern on a wafer; and
applying the mask pattern to a deterministic model of the lithography process to predict a characteristic of the printed pattern that is subject to local stochastic variations, wherein the deterministic model comprises (a) a deterministic compact model that predicts the characteristic of the printed pattern but does not account for the local stochastic variations of the characteristic, and (b) a deterministic correction to the predicted characteristic from the compact model that predicts the characteristic of the printed pattern as a function of model properties that include at least one stochastic model property that correlates to the local stochastic variations of the predicted characteristic.
