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 7):
The method of  claim 1 , wherein the angle of incidence of the first radiation beam on the metrology target is different than the angle of incidence of the second radiation beam on the metrology target.
