Patent ID: 7494938

Claim:
A method for forming a SiCOH dielectric on a substrate comprising: placing a substrate in a reactor; introducing a first precursor comprising atoms of Si, C, O and H, an oxidizing agent and an inert carrier into said reactor; and depositing a SiCOH dielectric film comprising atoms of Si, C, O and H and having a tri-dimensional network structure in which the material has a FTIR spectrum comprising a peak area for CH 3 +CH 2 stretching of less than about 1.40, a peak area for SiH stretching of less than about 0.20, a peak area for SiCH 3 bonding of greater than about 2.0, and a peak area for Si—O—Si bonding of greater than about 60%, and a porosity of greater than about 20% onto said substrate.
