Abstract:
In a method of determining an edge roughness parameter of a periodic structure, the periodic structure is illuminated ( 602 ) in an inspection apparatus. The illumination radiation beam may comprise radiation with a wavelength in the range 1 nm to 100 nm. A scattering signal ( 604 ) is obtained from a radiation beam scattered from the periodic structure. The scattering signal comprises a scattering intensity signal that is obtained by detecting an image of a far-field diffraction pattern in the inspection apparatus. An edge roughness parameter, such as Lined Edge Roughness and/or Line Width Roughness is determined ( 606 ) based on a distribution of the scattering intensity signal around a non-specular diffraction order. This may be done for example using a peak broadening model.

Claim (Index 26):
The method of  claim 25 , wherein the non-monochromatic radiation beam arises from a high-harmonic generation source.
