Abstract:
1. A method of forming a dielectric layer on a patterned substrate in a chamber, comprising: exposing the patterned substrate to a silicon-containing precursor in the presence of a plasma to deposit a carbon doped silicon oxide layer on the patterned substrate; purging the silicon-containing precursor from the chamber; treating the carbon doped silicon oxide layer with a plasma from an oxygen-containing gas; and repeating the exposing the patterned substrate to the silicon-containing precursor in the presence of the plasma to deposit the carbon doped silicon oxide layer, the purging the silicon-containing precursor from the chamber, and the treating the carbon doped silicon oxide layer until a desired thickness of the dielectric layer is obtained, wherein the silicon-containing precursor comprises one or more alkyl groups bonded to silicon.
