description Disclosed is a method and associated apparatus for measuring a characteristic of interest relating to a structure on a substrate. The method comprises calculating a value for the characteristic of interest directly from the effect of the characteristic of interest on the phase of illuminating radiation when scattered by the structure, subsequent to illuminating said structure with said illuminating radiation.
