摘要： A method for forming a protective film is provided. In the method, a source gas containing an organic metal gas or an organic semi-metal gas is supplied to a substrate having a plurality of recessed shapes formed in a surface so as to cause the source gas to adsorb on the surface of the substrate including the plurality of recessed shapes. Then, an oxidation gas is supplied to the surface of the substrate including the plurality of recessed shapes to oxidize the source gas adsorbed on the surface of the substrate, thereby depositing an oxidation film of the organic metal or the organic semi-metal on a flat area between the plurality of recessed shapes. Supplying the source gas to the substrate and supplying the oxidation gas to the substrate are repeated at a rate in a range of 90 to 300 cycles per minute.

摘要： A method of operating a film forming apparatus includes forming a carbon film on each of surfaces of a plurality of objects held by a holding unit in a processing container and performing a cleaning process with a cleaning gas to remove an unnecessary carbon film adhered on a inside of the processing container, wherein the method further includes, before the forming of the carbon film, forming, on a surface of a member contacting a processing space in the processing container, a tolerant pre-coating film which has a tolerance to the cleaning gas and improves adhesion of the carbon film to the surface of the member. Accordingly, the adhesion of the carbon film is improved, and further, the tolerant pre-coating film remains even when the cleaning process of removing the unnecessary carbon film is performed.

摘要： A method for manufacturing a semiconductor device includes forming a support on a side surface of a stack that extends from a substrate. The stack includes a second sacrificial film, plural first sacrificial films and plural silicon (Si)-containing films, wherein one first sacrificial film of the plural sacrificial films is stacked upon the second sacrificial film and the plural sacrificial films and the plural Si-containing films are alternately stacked upon one another, and at least a side of the second sacrificial film is not covered by the support, the one first sacrificial film and the substrate. The method further includes removing the second sacrificial film from the stack to form a space between the substrate and the one first sacrificial film and adjacent to the support, and filling the space with a dielectric film.
