Abstract :
Some possibilities of surface acoustic wave spectroscopy (SAWS) for thin films investigation are considered. Information value of SAWS method is dependent on the form of sound velocity dispersion curve. Non-linear dispersion curve allow obtaining of two values of four which describe film´s properties. Linear dispersion curve makes it possible to calculate only one film´s property. Special approach is presented to overcome this limitation. Boron carbonitride BCxNy and silicon carbonitride SiCxNyHz films are studied by SAWS. Their densities and Young´s modules are determined. The results are corresponding to known data on structure and composition of the films.
