Patent ID: 8557712

Claim:
A method of filling gaps on a substrate with dielectric material comprising: placing the substrate in a reaction chamber; introducing a process gas comprising a silicon-containing compound and an oxidant into the reaction chamber, wherein the oxidant is selected from oxygen (O 2 ) and ozone (O 3 ); exposing the substrate to a plasma generated from the process gas under conditions, including a substrate temperature of between about 60° C. and 100° C., such that the silicon-containing compound and the oxidant plasma species react and condense such that an amorphous flowable organo-silicon polymer film is thereby deposited to partially fill the gaps via a substantially-high frequency-only HF capacitatively-coupled plasma-assisted reaction; converting the flowable film to a dielectric material via an in-situ treatment process; and repeating the exposure and conversion operations at least once to fill the gaps.
