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 by adsorbing a reaction inhibitor onto a side wall of the gap, forming a first precursor layer by adsorbing a first reactant onto the 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. The reaction inhibitor includes a precursor material that does not react with a second reactant. The first reaction inhibition layer may have a density gradient in which a density of the reaction inhibitor decreases toward a bottom of the gap. The forming the first atomic layer includes adsorbing the second reactant onto the first precursor layer.
