  • Publication number: 20240087883
    Abstract: A method for forming a silicon-containing film in a recess formed on a surface of a substrate, the method includes: (a) forming a flowable film in the recess by exposing the substrate, which is adjusted to a first temperature, to plasma generated from a processing gas including a halogen-containing silane: and (b) curing the flowable film by thermally processing the substrate at a second temperature higher than the first temperature.
