Substrate processing method

Abstract

Disclosed is a method of processing a substrate, including: providing the substrate into a reaction space, the substrate comprising a gap having a predetermined cross-sectional area and a depth, performing a first sub-cycle step for depositing a gap-filling material by a predetermined thickness along a surface of the gap by an atomic layer deposition method, performing a second sub-cycle step for forming a deposition inhibiting region in an upper region of the gap using a deposition inhibitor and repeating a super-cycle such that a cross-sectional area of an inlet region of the gap remains greater than that of a lower region thereof located below the inlet region, the super-cycle comprising at least one the first sub-cycle and at least one the second sub-cycle, wherein the gap is filled without an occurrence of a void in the gap. Further, a substrate processing method for controlling a position of the void in the gap using the disclosed method above is disclosed.
