Abstract
A method for analysis includes directing a converging beam of X-rays toward a surface of a sample having an epitaxial layer formed thereon, and sensing the X-rays that are diffracted from the sample while resolving the sensed X-rays as a function of angle so as to generate a diffraction spectrum including a diffraction peak and fringes due to the epitaxial layer. A characteristic of the fringes is analyzed in order to measure a relaxation of the epitaxial layer.
