    摘要: Disclosed is a process for forming a silicon oxycarbide (SiOC) thin film on a substrate in a reaction space by a plurality of deposition cycles. At least one deposition cycle includes contacting a surface of the substrate with a silicon precursor that does not comprise nitrogen and a second reactant that includes reactive species. The reactive species are generated from a gas that flows continuously to the reaction space throughout the at least one deposition cycle. A ratio of a wet etch rate of the SiOC thin film to a wet etch rate of thermal silicon oxide is less than 5.

    摘要: Methods and systems for forming a structure including a silicon carbide layer and structures formed using the methods and systems are disclosed. Exemplary methods include providing a silicon carbide precursor to the reaction chamber, forming a plasma within the reaction chamber to form an initially flowable, viscous silicon carbide material on a surface of the substrate, wherein the initially viscous carbon material becomes the silicon carbide layer. Exemplary methods can include use of a silicon carbide precursor that includes a carbon-carbon triple bond and/or use of a relatively low plasma power density (e.g., less than 3 W/cm2).

    摘要: Exemplary semiconductor processing methods to clean a substrate processing chamber are described. The methods may include depositing a dielectric film on a first substrate in a substrate processing chamber, where the dielectric film may include a silicon-carbon-oxide. The first substrate having the dielectric film may be removed from the substrate processing chamber, and the dielectric film may be deposited on at least one more substrate in the substrate processing chamber. The at least one more substrate may be removed from the substrate processing chamber after the dielectric film is deposited on the substrate. Etch plasma effluents may flow into the substrate processing chamber after the removal of a last substrate having the dielectric film. The etch plasma effluents may include greater than or about 500 sccm of NF3 plasma effluents, and greater than or about 1000 sccm of O2 plasma effluents.

    摘要: A process for manufacturing a composite structure comprises: a) providing an initial substrate made of monocrystalline silicon carbide, b) epitaxially growing a monocrystalline silicon carbide donor layer on the initial substrate to form a donor substrate 111, c) implanting ions into the donor layer to form a buried brittle plane defining the the donor layer, d) depositing, using liquid injection-chemical vapor deposition at a temperature below 1000° C., a carrier layer on the donor layer, the carrier layer comprising an at least partially amorphous SiC matrix, e) separating the donor substrate along the brittle plane to form an intermediate composite structure comprising the donor layer on the carrier layer f) heat treating the intermediate composite structure at a temperature of between 1000° C. and 1800° C. to crystallize the carrier layer and form the polycrystalline carrier substrate, and g) applying mechanical and/or chemical treatment(s) of the composite structure.
