Abstract:
1. A process for depositing a continuous, abrasion, chemical and impact resistant silicon oxynitride coating on a substrate comprising: admixing silane (SiH providing a plasma chamber suitable for plasma-enhanced chemical vapor deposition which contains a substrate and a substrate support electrode; introducing said gas mixture into said plasma chamber at a plasma source at flow rates of 85 slm/4.5 slm/30 sccm (SiH wherein an optically transparent silicon oxynitride film of between about 10 and 5000 nm is formed on said substrate, said silicon oxynitride film having a refractive index of about 1.75, an atomic hydrogen content of less than 10% and a thickness uniformity on said substrate of about 5%.
