    摘要: Methods for forming silicon nitride hard masks are provided. The silicon nitride hard masks include carbon-doped silicon nitride layers and undoped silicon nitride layers. Carbon-doped silicon nitride layers that are deposited from a mixture comprising a carbon source compound, a silicon source compound, and a nitrogen source in the presence of RF power are provided. Also provided are methods of UV post-treating silicon nitride layers to provide silicon nitride hard masks. The carbon-doped silicon nitride layers and UV post-treated silicon nitride layers have desirable wet etch rates and dry etch rates for hard mask layers.

    摘要: The present invention generally provides a method for depositing a low dielectric constant film using an e-beam treatment. In one aspect, the method includes delivering a gas mixture comprising one or more organosilicon compounds and one or more hydrocarbon compounds having at least one cyclic group to a substrate surface at deposition conditions sufficient to deposit a non-cured film comprising the at least one cyclic group on the substrate surface. The method further includes substantially removing the at least one cyclic group from the non-cured film using an electron beam at curing conditions sufficient to provide a dielectric constant less than 2.5 and a hardness greater than 0.5 GPa.
