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 4):
The method as claimed in  claim 3 , wherein the measurement data and simulation data each comprises a plurality of intensity values, one for each combination of non-zeroth diffraction order, measurement radiation characteristic, and/or imposed target bias comprised in the target, and the intensity metric is derived from the intensity values.
