  • Publication number: 20230366094
    Abstract: An apparatus for depositing film stacks in-situ (i.e., without a vacuum break or air exposure) are described. In one example, a plasma-enhanced chemical vapor deposition apparatus configured to deposit a plurality of film layers on a substrate without exposing the substrate to a vacuum break between film deposition phases, is provided. The apparatus includes a process chamber, a plasma source and a controller configured to control the plasma source to generate reactant radicals using a particular reactant gas mixture during the particular deposition phase, and sustain the plasma during a transition from the particular reactant gas mixture supplied during the particular deposition phase to a different reactant gas mixture supplied during a different deposition phase.

  • Patent number: 11746420
    Abstract: An apparatus for depositing film stacks in-situ (i.e., without a vacuum break or air exposure) are described. In one example, an apparatus configured to deposit a plurality of film layers having different compositions on a substrate without exposing the substrate to a vacuum break between film deposition phases, is provided. The apparatus includes a process chamber, a plasma source and a process station reactant feed fluidically coupled to a gas inlet of the process station, and fluidically coupled to an inert gas delivery line, a first reactant mixture gas delivery line and a second reactant mixture gas delivery line such that the first reactant gas mixture and the second reactant gas mixture can be introduced sequentially into the process station reactant feed, and supplied via a shared path to the process station.

  • Publication number: 20220068636
    Abstract: Films that can be useful in large area gap fill applications, such as in the formation of advanced 3D NAND devices, involve processing a semiconductor substrate by depositing on a patterned semiconductor substrate a doped silicon oxide film, the film having a thickness of at least 5 gm, and annealing the doped silicon oxide film to a temperature above the film glass transition temperature. In some embodiments, reflow of the film may occur. The composition and processing conditions of the doped silicon oxide film may be tailored so that the film exhibits substantially zero as-deposited stress, substantially zero stress shift post-anneal, and substantially zero shrinkage post-anneal.
