摘要: A method for preparing silicon nitride films with improved properties and characterized by a limited concentration of hydrogen atoms, a high index of refraction, resistance to attack by a hydrofluoric solution, prevention of diffusion of alkalines and oxygen, and good dielectric properties such as optical gap. The process of preparation uses plasma CVD with ammonia. The invention can be applicable to flat screens, TFT transistors and functional glazings.
