  • Abstract
    The effects of gas flow and electrode spacing on the step coverage of silane-based nitride and oxynitride films formed by plasma-enhanced chemical-vapor deposition have been studied. It was found that the sidewall step coverage and sidewall film wet etch rate can be improved by varying these process parameters
