Abstract:
A method, involving illuminating at least a first periodic structure of a metrology target with a first radiation beam having a first polarization, illuminating at least a second periodic structure of the metrology target with a second radiation beam having a second different polarization, combining radiation diffracted from the first periodic structure with radiation diffracted from the second periodic structure to cause interference, detecting the combined radiation using a detector, and determining a parameter of interest from the detected combined radiation.

Claim (Index 13):
The apparatus of  claim 12 , wherein at least part of the second periodic structure does not overlie at least part of the first periodic structure and the center of the spot of the first radiation beam is incident on the at least part of the first periodic structure and the center of the spot of the second radiation beam is not incident on the at least part of the first periodic structure.
