    摘要: The present invention generally relates to low compressive stress doped silicate glass films for STI applications. By way of non-limited example, the stress-lowering dopant may be a fluorine dopant, a germanium dopant, or a phosphorous dopant. The low compressive stress STI films will generally exhibit a compressive stress of less than 180 MPa, and preferably less than about 170 MPa. In certain embodiment, the STI films of the invention will exhibit a compressive stress less than about 100 MPa. Further, in certain embodiments, the low compressive stress STI films of the invention will comprise between about 0.1 and 25 atomic % of the stress-lowering dopant.

    摘要: A process is provided for depositing an silicon oxide film on a substrate disposed in a process chamber. A process gas that includes a halogen source, a fluent gas, a silicon source, and an oxidizing gas reactant is flowed into the process chamber. A plasma having an ion density of at least 1011 ions/cm3 is formed from the process gas. The silicon oxide film is deposited over the substrate with a halogen concentration less than 1.0%. The silicon oxide film is deposited with the plasma using a process that has simultaneous deposition and sputtering components. The flow rate of the halogen source to the process chamber to the flow rate of the silicon source to the process chamber is substantially between 0.5 and 3.0.
