Abstract:
In a method for predicting at least one illumination parameter for evaluating an illumination setting for illuminating an object field of a projection exposure apparatus, illumination parameters are measured at a number of calibration settings, correction terms for prediction values of the illumination parameters are determined from the measured values, and then at least one illumination parameter of at least one illumination setting, which is not contained in the set of n calibration settings, is predicted.

Claim (Index 19):
A method for evaluating an illumination setting for illuminating an object field of a projection exposure apparatus, the projection exposure apparatus comprising an illumination system for generating a plurality of illumination settings with a plurality of illumination channels, the method comprising:\n providing correction terms for prediction values of a subset of the illumination parameters; measuring actual values of the illumination parameters at a number of calibration settings; determining correction terms for prediction values of a subset of the illumination parameters taking into account the measured values; updating the model taking into account the correction terms; predicting the illumination parameters for establishing a functional value of an evaluation function for an illumination setting depending on the illumination setting, the evaluation function being a function of predetermined illumination parameters; evaluating the illumination settings via the evaluation function on the basis of the predicted illumination parameters; and iteratively varying the illumination settings until a predetermined termination criterion is achieved.
