In the present work structural and electrical properties of thin films, deposited by PECVD from He-diluted S1H4+NH3+N2O gas mixtures, have been studied. Film compositions have been analyzed by NRA, RBS and hydrogen content has been determinated by ERDA while Infrared spectroscopy has been used to evaluate the local bonding configurations. Electrical properties have been measured in metal-insulator-metal structures by I-V ramp. From the results obtained, the oxynitride films show suitable properties for application as gate insulator in amorphous silicon thin film transistor.
