Abstract:
A method of depositing a layer of on a substrate comprising:placing a substrate on a substrate holder in a processing chamber, wherein an interior surface of a dielectric member forming a wall of the process chamber faces the substrate holder;supplying process gas into the processing chamber from a gas supply including a plurality of injectors having orifices, at least some of the orifices being in close proximity to the substrate and orienting the process gas along an axis of injection which intersects an exposed surface of the substrate at an acute angle such that a plurality of gas flows overlap each other in a plane parallel to the exposed surface of the substrate, the injectors injecting more of the process gas at the periphery of the substrate than in the middle of the substrate; andenergizing the process gas into the plasma state by inductively coupling RF energy through the dielectric member into the processing chamber, the process gas being plasma phase reacted with the exposed surface of the substrate such that a layer of material is deposited on the exposed surface.
