Abstract:
A process for the deposition of a multi-layer film on a substrate disposed in a processing chamber, said process comprising the steps of:depositing a first layer over the substrate;introducing a first set of process gases comprising a silicon-containing gas, an oxygen-containing gas and a nitrogen-containing gas into the processing chamber;applying energy to said first set of process gases to produce reaction of said first set of process gases to deposit a second layer over said first layer;maintaining said energy applied to said process gases for a period of time so as to deposit said second layer to a thickness which reduces reflection and refraction of incident radiant energy within a third layer, said third layer being formed over said second layer and said incident radiant energy causing a reaction in said third layer; andkeeping the substrate in the processing chamber throughout said process.
