Abstract

A method and an apparatus for filling a gap by using an atomic layer deposition (ALD) method are provided. The method includes forming a first reaction inhibition layer on a side wall of the gap; forming a first precursor layer by adsorbing a first reactant into a bottom of the gap and the side wall of the gap around the bottom of the gap; and forming a first atomic layer on the bottom of the gap and the side wall of the gap around the bottom of the gap by adsorbing a second reactant into the first precursor layer. The forming of the first reaction inhibition layer may include adsorbing a first reaction inhibitor into the side wall of the gap; and forming a second reaction inhibitor by removing a specific ligand from the first reaction inhibitor.
