Abstract:
A method of measuring a parameter of interest relating to a structure formed by a process on a substrate, and associated apparatuses. The method includes measuring the structure with measurement radiation including a first illumination acquisition setting (determining one or more selected from: a wavelength, a polarization or an incident angle of the measurement radiation) to obtain a first measurement value for the structure. The method further includes estimating, by applying a correction model to the first measurement value, at least a second measurement value for the structure corresponding to measurement of the structure with a second illumination acquisition setting different from the first illumination acquisition setting.

Claim (Index 6):
The method of  claim 5 , wherein the calibration phase comprises:\n measuring the calibration set of structures on the substrate with measurement radiation comprising one or more further illumination acquisition settings, additional to the first illumination acquisition setting and second illumination acquisition setting, wherein the correction model comprises a statistical correlation model relating measurements of the structure using the first illumination acquisition setting to measurements of the structure using the second illumination acquisition setting and to each of the further illumination acquisition settings, and wherein the estimating further comprising estimating, by applying the correction model to the first measurement value, a further measurement value for the structure corresponding to each further illumination acquisition setting.
