    摘要: An anti-loosening cylindrical threaded part includes internal and external threaded part. A cylindrical internal thread is arranged in inner hole of internal threaded part a cylindrical external thread is arranged on a screw of external threaded part, the inner hole of internal threaded part has cylindrical surface parallel to a longitudinal center axis of internal thread, and an inner diameter of cylindrical surface is greater than minimum inner diameter of internal thread. Surfaces of internal and external thread and cylindrical surface are not covered with anti-loosening materials. After internal and external thread are mutually screwed, cylindrical surface and a crest of external thread are mutually close contact structures, that is, a horizontal locking structure; therefore, loosening can be effectively prevented between cylindrical internal and external threaded part without longitudinal contractility of threaded part and a workpiece, and presently suitable for loosening prevention in various connections of the cylindrical threaded parts.

    摘要: Removing photoresist from a workpiece is described when a region of tungsten is exposed. A plasma is generated from a gas input consisting essentially of hydrogen gas and oxygen gas in a predetermined ratio. The plasma causes the photoresist to be removed from the workpiece while the region of tungsten is left substantially unmodified. The ratio of the hydrogen to oxygen can be adjusted to a particular value which causes the photoresist to be removed at about a maximum removal rate that corresponds to a minimum tungsten loss rate of about zero. Polysilicon oxidation in the presence of tungsten is described with little or no tungsten loss.

    摘要: In a technique for fabricating an integrated circuit to include an active device structure which supports an electrical interconnect structure, a photoresist layer is used prior to forming an electrical interconnect structure on the active device structure. The photoresist and related residues are removed by exposing the photoresist and exposed regions of the active device structure to one or more reactive species that are generated using a gas mixture including hydrogen gas, as a predominant source of the reactive species, in a plasma source such that the photoresist and residues are continuously exposed to hydrogen-based reactive species. An associated system architecture is described which provides for a substantial flow of hydrogen gas in the process chamber.

    摘要: In device fabrication, a photoresist layer is formed on an insulation layer, above a stop layer that is supported directly on an active device structure. Holes are needed through the insulation layer to reach a contact arrangement, defined by the active device structure in which each contact is covered by the stop layer and some of the contacts include a silicide material. A plurality of contact openings are etched through the insulation layer to expose the stop layer above each contact, which may produce etch related residue. The photoresist and residues are then stripped using a first plasma that contains oxygen, without removing the stop layer such that the stop layer protects the silicide material from the oxygen. Thereafter, etching is performed to remove the stop layer from the contacts using a second plasma that is oxygen free and which contains hydrogen.

    摘要: A method and apparatus for reducing the sensitivity of semiconductor processing to chamber conditions is provided. Process repeatability of common processes are affected by changing surface conditions which alter the recombination rates of processing chemicals to the chamber surfaces. In one aspect of the invention, a composition of one or more etchants is selected to optimize the etch performance and reduce deposition on chamber surfaces. The one or more etchants are selected to minimize buildup on the chamber surfaces, thereby controlling the chamber surface condition to minimize changes in etch rates due to differing recombination rates of free radicals with different surface conditions and achieve etch repeatability. In another embodiment, the etchant chemistry is adjusted to reduce the change to internal surface conditions after a cleaning cycle. In another embodiment, a process recipe is selected to reduce the sensitivity of the etch process to the chamber conditions. In another embodiment, chamber surface materials are selected to minimize the differences in recombination rates of free radicals on the surface materials and the byproduct depositions formed on the materials during processing.
