    摘要: A method of depositing a silica glass insulating film over a substrate. In one embodiment the method comprises exposing the substrate to a silicon-containing reactant introduced into a chamber in which the substrate is disposed such that one or more layers of the silicon-containing reactant are adsorbed onto the substrate; purging or evacuating the chamber of the silicon-containing reactant; converting the silicon-containing reactant into a silica glass insulating compound by exposing the substrate to oxygen radicals formed from a second reactant while biasing the substrate to promote a sputtering effect, wherein an average atomic mass of all atomic constituents in the second reactant is less than or equal to an average atomic mass of oxygen; and repeating the exposing, purging/evacuating and exposing sequence a plurality of times until a desired film thickness is reached.

    摘要: A method is provided for forming a fluorinated silicate glass layer with HDP-CVD having a lower dielectric constant without compromising the mechanical properties of hardness and compressive stress. A gaseous mixture comprising a silicon-containing gas, an oxygen-containing gas, and a fluorine-containing gas is provided to a process chamber. The ratio of the flow rate of the fluorine-containing gas to the flow rate of the silicon-containing gas is greater than 0.65. A high-density plasma is generated from the gaseous mixture by applying a source RF power having a power density less than 12 W/cm2. A bias is applied to a substrate in the process chamber at a bias power density greater than 0.8 W/cm2 and less than 2.4 W/cm2. The fluorinated silicate glass layer is deposited onto the substrate using the high-density plasma.

    摘要: A substrate processing system includes a housing defining a chamber for forming a film on the substrate surface of a substrate disposed within the chamber. The system includes a first plurality of nozzles that extend into the chamber for injecting a first chemical at a first distance from a periphery of the substrate surface, and a second plurality of nozzles that extend into the chamber for injecting a second chemical at a second distance from the periphery of the substrate surface. The second distance is substantially equal to or smaller than the first distance. In one embodiment, the first chemical contains a dielectric material and the second chemical contains dopant species which react with the first chemical to deposit a doped dielectric material on the substrate. Injecting the dopant species closer to the substrate surface than previously done ensures that the dopant species are distributed substantially uniformly over the substrate surface and the deposition of a stable doped dielectric layer.
