    摘要: 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 least one of a different pressure, oxygen concentration, or oxygen flow rate as the metal oxide forming.

    摘要: A metal-oxy-nitride seed dielectric layer can be formed on a metal-nitride lower electrode of a meta-insulator-metal (MIM) type capacitor. The metal-oxy-nitride seed dielectric layer can act as a barrier layer to reduce a reaction with the metal-nitride lower electrode during, for example, backend processing used to form upper levels of metallization/structures in an integrated circuit including the MIM type capacitor. Nitrogen included in the metal-oxy-nitride seed dielectric layer can reduce the type of reaction, which may occur in conventional type MIM capacitors. A metal-oxide main dielectric layer can be formed on the metal-oxy-nitride seed dielectric layer and can remain separate from the metal-oxy-nitride seed dielectric layer in the MIM type capacitor. The metal-oxide main dielectric layer can be stabilized (using, for example, a thermal or plasma treatment) to remove defects (such as carbon) therefrom and to adjust the stoichiometry of the metal-oxide main dielectric layer.

A first contact plug is formed on an inner wall and bottom of the contact hole. A second contact plug buries the contact hole and is formed on the first contact plug. A conductive layer is connected to the first contact plug and the second contact plug. The bottom thickness of the first contact plug formed on the bottom of the contact hole is thicker than the inner wall thickness of the first contact plug formed on the inner wall of the contact hole.

A first stress film is on the first gate electrode and the first source/drain areas of the first transistor area and at least a portion of the third gate electrode of the interface area. A second stress film is on the second gate electrode and the second source/drain areas of the second transistor area and not overlapping the first stress film on the third gate electrode of the interface area or overlapping at least a portion of the first stress film. The second stress film overlapping at least the portion of the first stress film is thinner than the second stress film in the second transistor area. Related methods are also described.
