摘要:
Silicon nitride film is formed on substrate by feeding trisilylamine and ammonia into a CVD reaction chamber that contains a substrate. The ammonia gas/trisilylamine gas flow rate ratio is set to a value of at least about 10 and/or the thermal CVD reaction is run at a temperature no greater than about 600° C. Silicon oxynitride is obtained by introducing an oxygen source gas into the CVD reaction chamber. This method avoids the production of ammonium chloride and/or the incorporation of carbonaceous contaminants which are detrimental to the quality of the deposited film.
