    摘要: In a method of forming a thin film using an atomic layer deposition (ALD) method, a thin film is formed on a substrate in cycles. Each cycle includes injecting a first reactant including an atom that forms the thin film and a ligand into a reaction chamber that includes the substrate, purging the first reactant, injecting a second reactant into the reaction chamber, and purging the second reactant. The thin film is formed by a chemical reaction between the atom that forms the thin film and a second reactant whose binding energy with respect to the atom that forms the thin film is larger than the binding energy of the ligand with respect to the atom that forms the thin film and the generation of by-products is prevented. The generation of a hydroxide by-product in the thin film is suppressed by using a material that does not include a hydroxide as the second reactant, purging the second reactant, and reacting the second reactant with a third reactant that includes hydroxide. After purging the second reactant, the third reactant for removing impurities and improving the stoichiometry of the thin film is injected and purged. In this way, it is possible to obtain a thin film that does not include impurities and whose stoichiometry is excellent.

    摘要: An apparatus for forming a film on a substrate includes a reaction chamber and gas supply lines. The gas supply lines supply gases for depositing and annealing the film. Depositing a dielectric film and annealing the dielectric film are performed in situ using the reaction chamber. Thus, the time required for forming the dielectric film is shortened, improving the productivity. Also, deposition and annealing of the dielectric film are performed in the same reaction chamber, so that less area is required for manufacturing equipment.

    摘要: A method for manufacturing a capacitor having a dielectric film formed of a tantalum oxide film. The method includes forming a lower electrode that is electrically connected to an active region of a semiconductor substrate. A pre-treatment film including a component selected from a group consisting of silicon oxide, silicon nitride, and combinations thereof, is formed on the surface of the lower electrode. A dielectric film is formed on the pre-treatment film using a Ta precursor. The dielectric film includes a first dielectric layer deposited at a first temperature selected from a designated temperature range, and a second dielectric layer deposited at a second temperature different from the first temperature and selected from the same designated temperature range. A thermal treatment is thereafter performed on the dielectric film in an oxygen atmosphere.
