Patent ID: 7501354

Claim:
A method for generating a low dielectric constant film, comprising: disposing a substrate within a processing chamber; providing an oxidizable silicon containing compound into the processing chamber; providing a carbon-containing precursor comprising at least one material selected from limonene, carene, cymene, fenchone, vinyl acetate, methyl methacrylate, ethyl vinyl ether, tetrahydrofuran, furan, 2,5 Norbornadiene, cyclopentene oxide, methyl cyclopentene, and 2-cyclopentene-1-one, into the processing chamber, wherein the carbon containing precursor excludes alpha-terpinene and avoids formation of a wax residue that is resistant to removal by plasma cleaning; reacting the oxidizable silicon containing compound and the carbon containing precursor with an oxidizing gas to form a carbon-doped dielectric film over the substrate; and annealing the substrate to create pores in the carbon-doped dielectric film.
