摘要： Disclosed is a substrate processing method comprising providing a substrate having a gap in a surface thereof into a reaction space, partially filling each of the plurality of gaps with a flowable silicon nitride film, forming a silicon oxide film partially filled in the gap by converting the silicon nitride film into the silicon oxide film, fully filling the gap, which is partially filled with the silicon oxide film, with a silicon nitride film, and forming a silicon oxide film to be fully filled in the gap, by converting the silicon nitride film into the silicon oxide film.

摘要： A substrate processing method includes providing a substrate having a gap structure into a reaction space, and supplying a silicon precursor and nitrogen reactant gas into the reaction space, and depositing a flowable silicon nitride film on the substrate to fill at least a part of the gap of the substrate, while maintaining an inside of the reaction space in a plasma state by applying radio frequency (RF) power in a pulsed mode, wherein as a duty ratio of the RF power decreases, fewer micropores are generated in the silicon nitride film in the gap.
