Abstract
The present invention provides a method of depositing a carbon doped silicon oxide film having a low dielectric constant (k). The concentration of oxygen is controlled to produce soft plasma conditions inside the chamber while a precursor gas is diverted through a bypass to stabilize the precursor gas flow prior to routing the precursor into the chamber and using a back to back plasma deposition scheme.
