Patent ID: 8889566

Claim:
A method of forming a dielectric layer on a patterned substrate, the method comprising: Transferring the patterned substrate into a substrate processing region; flowing a silicon precursor into the substrate processing region; flowing a plasma vapor/gas into the substrate processing region, wherein flowing the plasma vapor/gas and flowing the silicon precursor occur concurrently; striking a plasma in the substrate processing region by applying a plasma power less than or about 0.3 W per square centimeter of patterned substrate area; and forming the dielectric layer on the patterned substrate, wherein the dielectric layer comprises silicon and one of nitrogen or carbon and the dielectric layer is flowable during deposition, wherein flowing the silicon precursor comprises supplying a continuous flow of the silicon precursor to the substrate processing region throughout formation of the flowable dielectric layer, and wherein striking a plasma comprises applying a plasma power continuously throughout formation of the flowable dielectric layer.
