Abstract:
A process for depositing a low dielectric constant film, comprising decomposing one or more organosilicon compounds selected from a group consisting of octamethylcyclotetrasiloxane, hexamethyldisiloxane, bis(1-methyldisiloxanyl)methane, 2,4,6,8,10-pentamethylcyclopentasiloxane, 1,3,5,7-tetrasilano-2,6-dioxy-4,8-dimethylene, 2,4,6-trisilanetetrahydropyran, and 2,5-disilanetetrahydrofuran at a RF power density of at least about 0.03 W/cm2 and at a processing chamber pressure of between about 0.2 Torr and about 20 Torr to deposit a film comprising silicon, oxygen, and a carbon content of at least 1% by atomic weight.
