Classification: CPC H  C | IPC C  H

Claim 10:
11. A method of forming a silicon-and-carbon-containing material, the method comprising:
flowing a silicon-oxygen-and-carbon-containing precursor into a processing region of a semiconductor processing chamber, wherein a substrate is housed within the processing region of the semiconductor processing chamber;
forming a plasma within the processing region of the silicon-oxygen-and-carbon-containing precursor, wherein the plasma is formed at a frequency less than 13.56 MHz; and
depositing a silicon-and-carbon-containing material on the substrate, wherein the silicon-and-carbon-containing material as-deposited is characterized by a dielectric constant below 3.5 and a hardness of greater than 3 Gpa, wherein a deposition rate of the silicon-and-carbon-containing material is greater than 500 Å/min, and wherein the silicon-and-carbon-containing material as-deposited is characterized by a methyl incorporation less than 2.5%.
