Abstract:
Methods and apparatus for measuring a parameter of interest of a target structure formed on substrate are disclosed. In one arrangement, the target structure comprises a first sub-target and a second sub-target. The first sub-target comprises a first bias and the second sub-target comprises a second bias. The method comprises determining the parameter of interest using a detected or estimated reference property of radiation at a first wavelength scattered from the first sub-target and a detected or estimated reference property of radiation at a second wavelength scattered from the second sub-target. The first wavelength is different to the second wavelength.

Claim (Index 34):
The apparatus of  claim 28 , further comprising a measurement system configured to:\n detect the reference property of scattered radiation from the first sub-target at each of a first plurality of wavelengths to obtain a corresponding plurality of first sub-target measurements; and detect the reference property of scattered radiation from the second sub-target at each of a second plurality of wavelengths to obtain a corresponding plurality of second sub-target measurements, wherein the processor is configured to:\n use the plurality of first sub-target measurements to select the first wavelength; and \n use the plurality of second sub-target measurements to select the second wavelength.
