Abstract:
A metrology method, and associated metrology apparatus, that includes measuring a target formed in at least two layers on a substrate by a lithographic process and capturing at least one corresponding pair of non-zeroth diffraction orders, for example in an image field, to obtain measurement data. A simulation of a measurement of the target as defined in terms of geometric parameters of the target, the geometric parameters including one or more variable geometric parameters is performed and a difference between the measurement data and simulation data is minimized, so as to directly reconstruct values for the one or more variable geometric parameters.

Claim (Index 11):
The method as claimed in  claim 9 , comprising:\n calculating a spectral sequence describing a variation of an intensity parameter with wavelength of measurement radiation for the target with the layer height as determined in the minimizing; and optimizing the measurement radiation based on the spectral sequence.
