Claim 0:
1. An apparatus for depositing a silicon-carbon-containing film on a substrate, the apparatus comprising:
means for supporting the substrate in a reaction chamber;
means for generating a capacitively coupled plasma remote from the reaction chamber;
means for delivering a silicon-containing precursor into the reaction chamber; and
means for delivering radicals into the reaction chamber, wherein the silicon-containing precursor delivering means is located downstream of the radicals delivering means; and
a controller configured with instructions to perform the following operations:
flowing the silicon-containing precursor into the reaction chamber through the silicon-containing precursor delivery means, wherein the silicon-containing precursor comprises at least one of a silicon-silicon (Si—Si) bond or a silicon-hydrogen bond (Si—H) bond, and at least one of a silicon-carbon (Si—C) bond, a silicon-nitrogen (Si—N) bond, or a silicon-oxygen (Si—O) bond, wherein the silicon-containing precursor is free of carbon-oxygen (C—O) bonds and carbon-nitrogen (C—N) bonds;
generating plasma comprising hydrogen radicals in the capacitively coupled plasma generating means; and
delivering the hydrogen radicals into the reaction chamber through the radicals delivering means under conditions so that the hydrogen radicals react with the silicon-containing precursor to deposit the silicon-carbon-containing film on the substrate.
