Patent ID: 7326444

Claim:
A method of preparing a carbon doped silicon oxide (CDO) film on a substrate, the method comprising: (a) providing the substrate to a deposition chamber; and (b) contacting the substrate with one or more CDO precursors having a carbon-carbon triple bond and with an oxidizer under process conditions whereby the CDO film is formed on the substrate, and whereby the CDO film contains carbon-carbon triple bonds and their derivative bonds; wherein the substrate is contacted with one or more CDO precursors having a carbon-carbon triple bond and an oxidizer in a dual frequency plasma enhanced deposition process such that CDO film has carbon-carbon triple bonds or their derivative forms in sufficient amounts that the CDO film has a compressive stress or a tensile stress of between about −20 to 30 MPa and a dielectric constant of between about 2.5-3.0 has a cracking threshold of at least 3 um: and wherein the oxidizer is selected from the group consisting of O 2 , N 2 O, H 2 O, O 3 , H 2 O 2 , and combinations thereof.
