Abstract:
A method for depositing a film onto a substrate within a deposition chamber comprising the steps of:injecting a first process gas having a plurality of gas components into the chamber at a plurality of positions surrounding a substrate within the chamber; injecting a second process gas into the chamber at a first region spaced apart from and located generally centrally above the substrate; and injecting an oxygen-supplying gas into the chamber at a second region spaced apart from and located generally centrally above said substrate, wherein the plurality of gas components of the first process gas include first gas components and second gas components which are different gas components and which are injected into the chamber separately via a first set of nozzles for injecting the first gas components and a second set of nozzles for injecting the second gas components at the plurality of positions surrounding the substrate within the chamber.
