    摘要: Methods and apparatus of the present invention deposit fluorinated silicate glass (FSG) in such a manner that it strongly adheres to an overlying or underlying barrier layer or etch stop layer, and has a lower dielectric constant, among other benefits. In one embodiment, silicon tetrafluoride (SiF4), oxygen (O2), and argon (Ar) are used as the reactant gases, with the ratio of oxygen to silicon controlled to be at between about 2:1 to 6:1. Such O2 levels help reduce the amount of degradation of ceramic chamber components otherwise caused by the elimination of silane from the process recipe.

    摘要: A method and apparatus for forming a layer on a substrate in a process chamber during a plasma deposition process are provided. A plasma is formed in a process chamber, a process gas with precursor gases suitable for depositing the layer are flowed into the process chamber, and a magnetic field having a strength less than about 0.5 gauss is attenuated within the process chamber. Attenuation of such a magnetic field results in an improvement in the degree of process uniformity achieved during the deposition.
