  • Patent number: 10985013
    Abstract: Described herein is an apparatus comprising a plurality of silicon-containing layers wherein the silicon-containing layers are selected from a silicon oxide and a silicon nitride layer or film. Also described herein are methods for forming the apparatus to be used, for example, as 3D vertical NAND flash memory stacks. In one particular aspect or the apparatus, the silicon oxide layer comprises slightly compressive stress and good thermal stability. In this or other aspects of the apparatus, the silicon nitride layer comprises slightly tensile stress and less than 300 MPa stress change after up to about 800° C. thermal treatment. In this or other aspects of the apparatus, the silicon nitride layer etches much faster than the silicon oxide layer in hot H3PO4, showing good etch selectivity.

  • Publication number: 20190382886
    Abstract: The siloxanes containing compositions and methods are disclosed. The disclosed method relates to a method of depositing a dielectric film on a substrate, the method involving the steps of a) placing the substrate in a reaction chamber; b) introducing a process gas comprising a cyclic silicon-containing compound and an oxidant; and c) exposing the substrate to the process gas under conditions such that the cyclic silicon-containing compound and the oxidant react to form a flowable film on the substrate surface. The method can further involve converting the flowable film into a solid dielectric material (e.g., a silicon oxide film). In certain embodiments, conversion of the film may be accomplished by annealing the as-deposited film by a thermal, plasma anneal and/UV curing.
