    摘要: In a method of forming a titanium aluminum nitride layer, a first reactant is formed on a substrate by reacting a first source including titanium and a second source including nitrogen. A second reactant is formed by providing a third source including aluminum onto the substrate having the first reactant thereon and reacting the third source with the first reactant. A third reactant is formed by providing a fourth source including nitrogen onto the substrate having the second reactant thereon and reacting the fourth source with the second reactant. The titanium aluminum nitride layer having a good step coverage is formed on the substrate. Processes of forming the titanium aluminum nitride layer are simplified and deposition rate is improved. Therefore, a phase-change memory device using the titanium aluminum nitride layer as a lower electrode may have an improved throughput.

    摘要: A method of fabricating an integrated circuit device includes forming first and second patterns extending in first and second directions, respectively, on a target layer. The first patterns comprise a metal oxide and/or metal silicate material having an etch selectivity with respect to that of the target layer. The second patterns comprise a material having an etch selectivity with respect to those of the first patterns and the target layer. The target layer is selectively etched using the first patterns and the second patterns as an etch mask to define holes respectively extending through the target layer to expose a layer therebelow. At least one of the first and second patterns is formed using respective mask patterns formed by a photolithographic process, and the at least one of the first and second patterns have a finer pitch than that of the respective mask patterns.
