  • Patent number: 11605712
    Abstract: 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.

  • Publication number: 20070107845
    Abstract: A semiconductor processing system includes an intermediate structure disposed between an atmospheric pressure entrance transfer chamber and a vacuum common transfer chamber. The intermediate structure includes a transfer passage for a target substrate to pass therein. The transfer passage includes a first buffer chamber a middle transfer chamber and a second buffer chamber detachably connected. An additional processing apparatus is detachably connected to the middle transfer chamber. The intermediate structure is selectively arranged in first or second state. In the first state, the additional processing apparatus performs a vacuum process, while the first buffer chamber is a load-lock chamber. In the second state, the additional processing apparatus performs an atmospheric pressure process, while the second buffer chamber is a load-lock chamber.
