Abstract: A method and system for forming a film on a substrate are disclosed. Exemplary methods include using a first plasma condition to form a layer of deposited material having a good film thickness uniformity, using a second plasma condition to treat the deposited material and thereby form treated material, and using a third plasma condition to form a surface-modified layer—e.g., reactive sites on the treated material.

Abstract: Provided is a substrate processing method capable of filling a film in a gap structure without forming voids or seams in a gap, the substrate processing method including: a first step of forming a thin film on a structure including a gap by performing a first cycle including supplying a first reaction gas and supplying a second reaction gas to the structure a plurality of times; a second step of etching a portion of the thin film by supplying a fluorine-containing gas onto the thin film; a third step of supplying a hydrogen-containing gas onto the thin film; a fourth step of supplying an inhibiting gas to an upper portion of the gap; and a fifth step of forming a thin film by performing a second cycle including supplying the first reaction gas and supplying a second reaction gas onto the thin film a plurality of times.

Abstract: A thin film forming method includes: a first operation of supplying a source gas at a first flow rate into a reactor; a second operation of purging the source gas in the reactor to an exhaust unit; a third operation of supplying a reactive gas at a second flow rate into the reactor; a fourth operation of supplying plasma into the reactor; and a fifth operation of purging the reactive gas in the reactor to the exhaust unit, wherein, during the second to fifth operations, the source gas is bypassed to the exhaust unit, and a flow rate of the source gas bypassed to the exhaust unit is less than the first flow rate. According to the thin film forming method, the consumption of the source gas and the reactive gas may be reduced, and the generation of reaction by-products in the exhaust unit may be minimized.

Abstract: A substrate processing method of forming an air gap includes: forming deposition inhibitor sites in a lower space between a first protrusion and a second protrusion; and forming film-forming sites and an interlayer insulating layer on the first protrusion and the second protrusion, wherein the interlayer insulating layer is selectively formed in an upper space between the first protrusion and the second protrusion by the deposition inhibitor sites and the film-forming layer, and thus an air gap is formed between the first protrusion and the second protrusion.
