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.

Substrate processing method

A substrate processing method capable of achieving uniform etch selectivity in the entire thickness range of a thin film formed on a stepped structure includes: forming a thin film on a substrate by performing a plurality of cycles including forming at least one layer and applying plasma to the at least one layer under a first process condition; and applying plasma to the thin film under a second process condition different from the first process condition.

A substrate processing method with an improved etch selectivity includes: a first operation for forming a film on a stepped structure having a top surface, a bottom surface, and a side surface connecting the top surface and the bottom surface, wherein a first atmosphere is set to reduce a mean free path of plasma ions and to cause the plasma ions to have no directionality; and a second operation for changing a bonding structure of a portion of the film, wherein a second atmosphere is set to cause the plasma ions to have directionality, wherein the first operation is repeated a plurality of times, the second operation is performed for a predetermined time period, the first operation and the second operation form a group cycle, and the group cycle is repeated by a plurality of times.

Method for manufacturing a semiconductor device

A thin film deposition method with respect to a substrate including a pattern structure includes supplying RF power through a component disposed below a substrate, forming a potential on an exposed surface of the substrate exposed to a reaction space, moving the active species to the exposed surface in the reaction space using the potential, and forming a thin film including active species component on the exposed surface of the substrate.
