    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 for cleaning silicon carbide and/or organosilicate layers from interior surfaces of a process chamber is disclosed. In one aspect, silicon carbide and/or organosilicate layers are cleaned from interior surfaces of a process chamber by treating it with a hydrogen/fluorine-based plasma. In another aspect, silicon carbide and/or organosilicate layer are cleaned from interior surfaces of the process chamber by treating it with a hydrogen-based plasma followed by a fluorine-based plasma. Alternatively, silicon carbide and/or organosilicate layers are cleaned from interior surfaces of the chamber by treating it with a fluorine-based plasma followed by a hydrogen-based plasma.

    摘要: A method of forming an integrated circuit using a fluoro-organosilicate layer is disclosed. The fluoro-organosilicate layer is formed by applying an electric field to a gas mixture comprising a fluoro-organosilane compound and an oxidizing gas. The fluoro-organosilicate layer is compatible with integrated circuit fabrication processes. In one integrated circuit fabrication process, the fluoro-organosilicate layer is used as a hardmask. In another integrated circuit fabrication process, the fluoro-organosilicate layer is incorporated into a damascene structure.

    摘要: A plasma reactor is described that includes a vacuum chamber defined by an enclosure including a side wall and a workpiece support pedestal within the chamber defining a processing region overlying said pedestal. The chamber has at least a first pair of ports near opposing sides of said processing region and a first external reentrant tube is connected at respective ends thereof to the pair of ports. The reactor further includes a process gas injection apparatus (such as a gas distribution plate) and an RF power applicator coupled to the reentrant tube for applying plasma source power to process gases within the tube to produce a reentrant torroidal plasma current through the first tube and across said processing region. A magnet controls radial distribution of plasma ion density in the processing region, the magnet having an elongate pole piece defining a pole piece axis intersecting the processing region.

    摘要: A method of forming an optical marker layer for etch endpoint determination in integrated circuit fabrication processes is disclosed. The optical marker layer is used in conjunction with organic and/or carbon-containing material layers that are used as bulk insulating materials and barrier materials. The optical marker layer is formed on the bulk insulating material layer and/or the barrier material layer by incorporating an optical marker into the surface thereof. The optical marker is incorporated into the surface of the bulk insulating material layer and/or the barrier material layer by treating such layer with an optical marker-containing gas. The optical marker layer provides an optical marker emission spectrum when it is etched during a subsequent patterning step.
