Abstract:
A method of determining a patterning process parameter from a metrology target, the method including: obtaining a plurality of values of diffraction radiation from the metrology target, each value of the plurality of values corresponding to a different illumination condition of a plurality of illumination conditions of illumination radiation for the target; and using the combination of values to determine a same value of the patterning process parameter for the target.

Claim (Index 19):
The method of  claim 18 , wherein the images include one or more derived images, each of the one or more derived images being obtained from a linear combination of two or more acquired images so as to remove information relating to portions of an acquisition illumination profile of at least one of the acquired images which overlaps with an acquisition illumination profile relating to another of the acquired images, the acquisition illumination profiles comprising the actual illumination profiles used in acquisition of the acquired images.
