摘要： The present invention meets these needs by providing improved methods of filling gaps. In certain embodiments, the methods involve placing a substrate into a reaction chamber and introducing a vapor phase silicon-containing compound and oxidant into the chamber. Reactor conditions are controlled so that the silicon-containing compound and the oxidant are made to react and condense onto the substrate. The chemical reaction causes the formation of a flowable film, in some instances containing Si—OH, Si—H and Si—O bonds. The flowable film fills gaps on the substrates. The flowable film is then converted into a silicon oxide film, for example by plasma or thermal annealing. The methods of this invention may be used to fill high aspect ratio gaps, including gaps having aspect ratios ranging from 3:1 to 10:1.

摘要： A method of cleaning a plasma etching reactor is provided. The method of cleaning a plasma etching reactor includes generating one or more plasmas from oxygen gas and a hydrogen-containing gas, and exposing interior surfaces of the reactor to the plasma(s) from the oxygen-gas and the hydrogen-containing gas. The cleaning method is used to remove deposited material, such as deposits containing fluorine, carbon, oxygen, and hydrogen from interior surfaces of the reactor. The hydrogen-containing gas may contribute to the cleaning method by providing a source of hydrogen that removes fluorine from the surfaces of the reactor.

摘要： A method and apparatus for depositing a low dielectric constant film by reaction of an organosilicon compound and an oxidizing gas at a constant RF power level from about 10 W to about 200 W or a pulsed RF power level from about 20 W to about 500 W. Dissociation of the oxidizing gas can be increased prior to mixing with the organosilicon compound, preferably within a separate microwave chamber, to assist in controlling the carbon content of the deposited film. The oxidized organosilane or organosiloxane film has good barrier properties for use as a liner or cap layer adjacent other dielectric layers. The oxidized organosilane or organosiloxane film may also be used as an etch stop and an intermetal dielectric layer for fabricating dual damascene structures. The oxidized organosilane or organosiloxane films also provide excellent adhesion between different dielectric layers. A preferred oxidized organosilane film is produced by reaction of methylsilane, CH3SiH3, dimethylsilane, (CH3)2SiH2, or 1,1,3,3-tetramethyl-disiloxane, (CH3)2—SiH—O—SiH—(CH3)2, and nitrous oxide, N2O, at a constant RF power level from about 10 W to about 150 W, or a pulsed RF power level from about 20 W to about 250 W during 10% to 30% of the duty cycle.

摘要： An exemplary method and apparatus for abating reaction products from a vacuum processing chamber includes a reaction chamber in fluid communication with the vacuum processing chamber, a coil disposed about the reaction chamber, and a power source for supplying RF energy to the coil. The coil creates a plasma in the reaction chamber which effectively breaks down stable reaction products from the vacuum processing chamber such as perfluorocarbons (PFCs) and hydrofluorocarbons (HFCs) which significantly contribute to global warming. According to alternative embodiments, the plasma may be generated with grids or coils disposed in the reaction chamber perpendicular to the flow of reaction products from the vacuum processing chamber.
