Thermal chemical vapor deposition of silicon nitride

摘要

Apparatus comprising a processing region, a substrate support, a gas delivery system, a gas mixing region, a heating element positioned to heat an adapter ring fastened to a face plate to a desired temperature, and a temperature controlled exhaust system. Also, a method and apparatus for vaporizing bis(tertiary-butylamino)silane, flowing the bis(tertiary-butylamino)silane and ammonia into a processing chamber, combining the two reactants having an additional mixing region defined by an adapter ring and at least two blocker plates, heating the adapter ring, and flowing the bis(tertiary-butylamino)silane through a gas distribution plate into a processing region.
