Abstract:
A projection objective having a number of adjustable optical elements is optimized with respect to a number of aberrations by specifying a set of parameters describing imaging properties of the objective, each parameter in the set having an absolute value at each of a plurality of field points in an image plane of the projection objective. At least one of the optical elements is adjusted such that for each of the parameters in the set, the field maximum of its absolute value is minimized.

Claim (Index 20):
A microlithography projection exposure machine, comprising:\n an illumination device for illuminating a reticle; a projection objective comprising a plurality of optical elements for projecting an image of the reticle onto a substrate in an image field at an image plane of the projection objective; a plurality of manipulators each configured to move either the reticle or a corresponding one of the optical elements of the projection objective; and a control unit configured to adjust the projection exposure machine between different configurations by causing one or more of the manipulators to adjust a position of the reticle and/or at least one of the optical elements of the projection objective, the different configurations comprising an initial configuration and a second configuration, wherein, in the initial configuration, a maximum value at least one field point among a plurality of different field points in the image field for an absolute value of a parameter indicative of a performance of the projection exposure machine exceeds a specified field maximum value, the parameter being a lithographic process parameter or an image-forming parameter of the projection objective, and in the second configuration, a largest absolute value for every one of the plurality of different field points is less than the specified field maximum value.
