  • Publication number: 20030049943
    Abstract: A method of forming a dielectric film composed of metal oxide under an atmosphere of activated vapor containing oxygen. In the method of forming the dielectric film, a metal oxide film is formed on a semiconductor substrate using a metal organic precursor and O2 gas while the semiconductor substrate is exposed under activated vapor atmosphere containing oxygen, and then, the metal oxide film is annealed while the semiconductor substrate is exposed under activated vapor containing oxygen. The annealing may take place in situ with the formation of the metal oxide film, at the same or substantially the same temperature as the metal oxide forming, and/or at at least one of a different pressure, oxygen concentration, or oxygen flow rate as the metal oxide forming.

    Abstract: A semiconductor device includes a first electrode formed of a silicon-family material, a dielectric layer formed by sequentially supplying reactants on the first electrode, and a second electrode having a work function larger than that of the first electrode, with the second electrode being formed on the dielectric layer. The first electrode and the second electrode can be a lower electrode and an upper electrode, respectively, in a capacitor structure. Also, the first electrode and the second electrode can be a silicon substrate and a gate electrode, respectively, in a transistor structure. A stabilizing layer, which is, for example, a silicon oxide layer, a silicon nitride layer, or a composite layer of the silicon oxide layer and the silicon nitride layer, for facilitating the formation of the dielectric layer by hydrophilizing the surface of the first electrode, may be formed on the first electrode. The dielectric layer can be formed by an atomic layer deposition method.

  • Patent number: 6416584
    Abstract: 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.

    Abstract: Methods of manufacturing integrated circuit capacitors having low equivalent oxide thickness (Toxeq) and excellent leakage current characteristics include forming a lower capacitor electrode on a semiconductor substrate and then forming a capacitor dielectric layer on the lower capacitor electrode. An upper capacitor electrode, comprising ruthenium (Ru), is then formed on the capacitor dielectric layer. The step of forming an upper capacitor electrode is preceded by the step of heat treating the metal oxide dielectric layer in an oxygen containing ambient at a temperature in a range between about 100° C. and about 600° C. This heat treatment step is preferably performed in order to incorporate additional quantities of oxygen into the metal oxide dielectric layer, so that the metal oxide dielectric layer is enriched with oxygen.
