METHOD OF FORMING A LAYER AND METHOD OF MANUFACTURING A CAPACITOR USING THE SAME

摘要

In a method of forming a layer and a method of manufacturing a capacitor using the same, a preliminary zirconium oxide film is formed on a substrate by introducing a first reactant including a zirconium precursor, and a first oxidant onto the substrate. A thermal treatment is performed on the preliminary zirconium oxide film to form a first zirconium oxide film having a dense and crystalline structure. An aluminum oxide film is formed on the first zirconium oxide film by introducing a second reactant including an aluminum precursor, and a second oxidant onto the substrate. The thermally-treated layer including the first zirconium oxide film and the aluminum oxide film may form a dielectric layer of a capacitor.
