Abstract:
In an aspect, a plurality of parameters characteristic of the patterned wafer are determined based on measurements of the intensity of electromagnetic radiation after the diffraction thereof at the patterned wafer. The intensity measurements are carried out for at least one used structure and at least one auxiliary structure. The parameters are determined based on intensity values measured during the intensity measurements for respectively different combinations of wavelength, polarization and/or order of diffraction, and also on the basis of correspondingly calculated intensity values, with a mathematical optimization method being applied.

Claim (Index 19):
A method, comprising:\n determining, for a used structure of a patterned wafer and an auxiliary structure of the patterned wafer, a plurality of parameters characteristic of the patterned wafer based on: i) intensity measurements of electromagnetic radiation diffracted at the patterned wafer; and ii) correspondingly calculated intensity values via a mathematical optimization method, wherein:\n the measured intensity of the electromagnetic radiation comprises respectively different combinations of wavelength, polarization and/or order of diffraction; and \n the method comprises, for a partial region of the patterned wafer, comparing the measured intensity values for the partial region with intensity values obtained for a reference.
