Abstract: A method includes determining topographic information of a substrate for use in a lithographic imaging system, determining or estimating, based on the topographic information, imaging error information for a plurality of points in an image field of the lithographic imaging system, adapting a design for a patterning device based on the imaging error information. In an embodiment, a plurality of locations for metrology targets is optimized based on imaging error information for a plurality of points in an image field of a lithographic imaging system, wherein the optimizing involves minimizing a cost function that describes the imaging error information. In an embodiment, locations are weighted based on differences in imaging requirements across the image field.

Abstract: Disclosed is a substrate comprising a target structure formed in at least two layers. The target structure comprises a first region comprising periodically repeating features in each of said layers measureable using optical metrology; and a second region comprising repetitions of one or more product features in each of said layers, said repetitions being sufficient for stochastic analysis to determine at least one local variation metric. The method also comprises a method of determining a correction for control of a lithographic process based on measurement of such a target structure.
