Abstract:
An apparatus and method for performing a measurement operation on a substrate in accordance with one or more substrate alignment models. The one or more substrate alignment models are selected from a plurality of candidate substrate alignment models. The apparatus, which may be a lithographic apparatus, includes an external interface which enables selection of the substrate alignment model(s) and/or alteration of the substrate alignment model(s) prior to the measurement operation.

Claim (Index 9):
The apparatus as claimed in  claim 8 , configured such that the comparison determines whether modelled post-exposure measurement data correlates to the pre-exposure measurement data; and configured to:\n attribute errors to substrate deformation if the modelled post-exposure measurement data correlates with the pre-exposure measurement data; and attribute errors to deformation of one or more measurement targets on the substrate if the modelled post-exposure measurement data does not correlate with the pre-exposure measurement data; the apparatus further configured such that the selection of the substrate alignment model(s) is dependent at least in part on whether the errors are attributed to deformation of one or more measurement targets or attributed to substrate deformation.
