Abstract:
A method of performing metrology analysis of a thin film includes coupling a radiation into an optical element disposed adjacent to a surface of the thin film. The radiation is coupled such that the radiation is totally internally reflected at an interface between the optical element and the thin film. An evanescent radiation generated at the interface penetrates the thin film. The method furthers include analyzing the evanescent radiation scattered by the thin film to obtain properties of the thin film.

Claim (Index 18):
The method of  claim 17 , wherein properties of the thin film obtained comprise at least one selected from the group consisting of a critical dimension of a pattern formed on the thin film, a shape of the pattern formed on the thin film, an impurity present in the thin film, a chemical composition of the thin film, a size of a defect present in the thin film and a density of the defect present in the thin film.
