Abstract: Optical measurement of a sample that includes a structure-of-interest (SOI) optically coupled to a section having an unknown structure is optically measured using an influence map of the deviation contribution from the unknown structure. The influence map is generated by obtaining metrology data for a plurality of locations that include the SOI and unknown structure and determining the deviation contribution at each location by decoupling the deviation contribution from base contributions from the SOI and unknown structure. During measurement of a location, the deviation contribution associated with that location may be obtained from the influence map and removed from the measured data. The processed data may be fit with a model that includes a rigorous model for the SOI and an effective model for the base contribution of the unknown structure to determine one or more parameters of the SOI.
