Claim:
1. A method of manufacturing an oxide layer of a semiconductor device, comprising: forming a stacked structure that includes a plurality of channels extending through a plurality of insulating interlayer patterns and gate electrodes alternately stacked on each other on a substrate, the plurality of insulating interlayer patterns and gate electrodes defining at least one opening that exposes a portion of the substrate; providing a preliminary precursor flow on an innerwall of the at least one opening to form a preliminary precursor layer on the innerwall; providing a precursor flow and a first oxidizing agent flow on the preliminary precursor layer alternately and repeatedly to form precursor layers and first oxidizing agent layers alternately stacked on each other, the first oxidizing agent flow including a mixture gas of hydrogen (H providing a second oxidizing agent flow on the precursor layers and first oxidizing agent layers alternately stacked on each other to form a filling layer in the opening.
