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 18):
The apparatus of  claim 8 , wherein the control system configured to determine a parameter of interest from the detected combined radiation is configured to determine a parameter of interest for the target from the combined radiation and determine a parameter of interest specific to the first periodic structure and/or the second periodic structure from the combined radiation.
