摘要:
An integrated circuit capacitor is manufactured by forming a lower electrode on a substrate and forming a metal preprocessed layer on the lower electrode using chemical vapor deposition in which a metal precursor is used as a source gas and the metal precursor comprises oxygen. A dielectric layer is then formed on the metal preprocessed layer and an upper electrode is formed on the dielectric layer. The metal preprocessed layer may reduce oxidation of the lower electrode due to oxygen supplied during formation of the dielectric layer.

A microelectronic capacitor is formed by forming a first tantalum pentoxide film on a conductive electrode and annealing the first tantalum pentoxide film in the presence of ultraviolet radiation and ozone. The forming step and annealing step are then repeated at least once to form at least a second tantalum pentoxide film which has been annealed in the presence of ultraviolet radiation, on the first tantalum pentoxide film. A second conductive electrode may then be formed on the tantalum pentoxide layer. The resultant tantalum pentoxide layer can have a thickness which exceeds 45 .ANG., yet has a reduced leakage current by filling the oxygen vacancies across the thickness thereof.

Semiconductor capacitors comprise first electrodes, second electrodes, and tantalum oxide layers positioned between the first electrodes and the second electrodes. The tantalum oxide layers are formed by depositing at least one precursor and ozone gas, the at least one precursor represented by the formula: wherein X is selected from the group consisting of nitrogen, sulfur, oxygen, and a carbonyl group; and wherein R1 and R2 are independently alkyl.
摘要:
A microelectronic capacitor is formed by nitrating the surface of a conducting electrode on a microelectronic substrate. The nitrated surface of the conductive electrode is then oxidized. The nitrating and oxidizing steps collectively form a film of silicon oxynitride on the conductive electrode. A tantalum pentoxide film is then formed on the oxidized and nitrated surface of the conductive electrode. The tantalum pentoxide film may then be thermally treated in the presence of oxygen gas. High performance microelectronic capacitors are thereby provided.
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.
