The films of a new ternary compound, silicon carbonitride, were synthesized by means of plasma enhanced deposition (PECVD) using hexamethyldisilazane Si2NH(CH3)6 as the precursor. Different investigation methods, namely, IR and Raman spectroscopy, XPS, ellipsometry, electron microscopy, including high-resolution me-thods (HRTEM, SAED) were applied to study physico-chemical properties of the films. Much attention was paid to the development of the X-ray phase analysis methods involving synchrotron radiation to determine the structure and phase composition of thin films. It was established that the silicon carbonitride films contain nanocrystals 2-5 nm in size distributed over the amorphous matrix.
