Abstract:
A substrate having a substantially ammonia-free silicon oxynitride passivation film having a refractive index of between 1.5 and 1.9 and a wet etch rate of below about 3000 angstroms per minute deposited thereon by a chemical vapor deposition method comprisingemploying a first and second electrode for reacting at a deposition temperature of less than about 250.degree. C. and at a deposition pressure of between about 0.5 and 3.5 Torr a reaction gas mixture of silane, nitrogen and nitrous oxide that is substantially ammonia free, whereby a separation of said first and second electrodes is substantially less than a lateral size of said substrate to preclude the use of magnetic field enhancement with said method for depositing.
