Claim 0:
1. A method for use in measuring one or more characteristics of a patterned structure, the method comprising:
performing measurements on a patterned structure by illuminating the patterned structure with exciting light to cause Raman scattering of one or more excited regions of the patterned structure, while applying a controlled change of a temperature condition of the patterned structure and while monitoring the temperature condition of the patterned structure;
collecting the Raman scattering, by a detection unit, and generating measured data; and
generating, utilizing the measured data, data indicative of spatial profile of one or more properties of the patterned structure;
wherein the measured data is a temperature dependent Raman response of the patterned structure, and
wherein said monitoring of the temperature comprises analyzing the temperature dependent Raman response of the patterned structure and determining the controlled change of the temperature condition from a variation of at least one of (a) Raman scattering peak intensity, (b) Raman scattering peak wavelength, or (c) Raman scattering peak width.
