Abstract
Disclosed is a method of determining a substrate deformation metric relating to at least one substrate, the substrate deformation metric describing deformation across the at least one substrate. The method comprises obtaining alignment data relating to measurement of a plurality of structures on said substrate using a plurality of illumination conditions; and determining substrate deformation metric values for the substrate deformation metric which minimizes the number of basis vectors which are required to expand dispersion due to structure deformation of said plurality of structures.
