Patent ID: 8143174

Claim:
A method of depositing dielectric material upon a substrate, comprising: providing the substrate to a deposition chamber; introducing a process gas in the deposition chamber, the process gas comprising an organosilane precursor selected from the group consisting of methylsilane, dimethylsilane, trimethylsilane, tetramethylsilane, and phenylmethylsilane, the deposition chamber having a first pressure and a first temperature about 125° C. or less during a first time period while depositing a carbon-doped silicon oxide layer; and maintaining the process gas in the deposition chamber, the deposition chamber having a second pressure and a second temperature for a second time period while depositing the carbon-doped silicon oxide layer, the carbon-doped silicon oxide layer having a carbon content of at least about 8 atomic percent or more, wherein the first pressure is higher than the second pressure and the first temperature is less than the second temperature.
