摘要: Silicon carbonitride films are synthesized by plasma enhanced chemical vapor deposition from bis(trimethylsilyl)ethylamine and helium or ammonium mixtures. The structure of bonds in the is studied X-ray photoelectron IR spectroscopy. data on main types present silicon deposited under different synthesis conditions obtained. It shown that use ammonia at a low temperature provides with simultaneous formation Si-C, Si-N, C-N bonds. obtained mixture Si-C Si-N. high temperatures close to SiCx regardless type additional gas used.
