Abstract:
1. A method for depositing a low dielectric constant film on a substrate, comprising reacting two or more organosiloxanes, wherein at least one of the organosiloxanes is a cyclic organosiloxane comprising C, H, and O, and wherein the two or more organosiloxanes are selected from the group consisting of 1,3,5,7-tetramethylcyclotetrasiloxane, octamethylcyclotetrasiloxane, 1,3,5,7,9-pentamethylcyclopentasiloxane, and 1,3,5,7-tetrasilano-2,6-dioxy-4,8-dimethylene, while applying RF power, wherein the low dielectric constant film comprises silicon-carbon bonds and a dielectric constant of about 3 or less.
