    摘要: The present invention provides a method and apparatus for limiting residue build-up by lining with a ceramic material the exhaust plenun and exhaust manifold of a processing chamber. In another aspect of the invention, the inventors have used an air gap between the ceramic liner and the processing chamber walls to increase the dielectric value of the ceramic liner, and further inhibit the build-up of residues. In another aspect, the ceramic liner has been found to retain sufficient heat to allow the elimination of heaters typically used to heat the aluminum walls during a clean operation, if the clean operation is commenced immediately after a process step so that the ceramic retains the necessary heat from the previous processing step. The provision of an air gap aids in this heating, preventing the ceramic heat from being drawn off by direct contact with the aluminum walls. In a preferred embodiment, the ceramic liners are attached to the chamber walls with TEFLON.RTM. (polytetrafluoroethylene) screws.

The apparatus includes a depositing thin-film particle source, a beam-defining aperture between the particle source and the deposited substrate(s), and a substrate holder to rotate the substrate(s) around its center and move the center along a lateral path so that the substrate(s) can scan across the particle beam from one substrate edge to the other edge. The method includes a step of providing a vacuum chamber for containing a thin-film particle source for generating thin-film particles to deposit a thin-film on the substrates. The method further includes a step of containing a substrate holder in the vacuum chamber for holding a plurality of substrates having a thin-film deposition surface of each substrate facing the beam of thin-film particles. The method further includes a step of providing a rotational means for rotating the substrate holder to rotate each of the substrates exposed to the thin-film particles for depositing a thin film thereon. And, the method further includes a step of providing a laterally reciprocal moving means for reciprocally moving said substrate holder for said beam traversing on said substrate holder from one side of the edge to the other side of the edge or at least passing through the central area of said substrate holder.

    摘要: A plasma etch chemistry and etch methodology is provided to improve critical dimension control for openings formed into and/or through a semiconductor thin film. According to an embodiment, the plasma etch chemistry includes an etchant mixture comprising a first etchant of the formula CxHyFz (where x≧2, y≧1 and z≧2) and a second etchant other than the first etchant to form the openings. The relationship of x, y and z may be such that y+z equals an even number ≦2x+2. According to an alternative embodiment, the plasma etch chemistry further includes strained cyclic (hydro)fluorocarbon. The plasma etch chemistry may be used to form openings in the layer in a single-etch step. In a further embodiment, the plasma etch chemistry described herein may etch less than the entire thickness of the layer, and a second plasma etch chemistry substantially free of the first etchant and strained cyclic (hydro)fluorocarbons etches the remainder of the layer to form the openings. Such an etch methodology advantageously reduces the risk of etching the materials underlying the layer.

    摘要: A method of reducing impurities in films to be deposited within a chemical vapor deposition (CVD) device includes steps of cleaning the process chamber of the CVD device, and depositing, prior to wafer processing, a gettering layer of, for example, phosphorous containing glass on interior surfaces of the process chamber. The gettering layer getters mobile alkali ions and substantially reduces or prevents outdiffusion of alkali ions and other impurities. The phosphorous containing glass may also be doped with boron. A blocking layer, such as undoped silicate glass, silicon nitride, silicon oxynitride or the like may be deposited on the gettering layer to trap impurities and to prevent phosphorous contamination in a applications sensitive to such contamination. Alternatively, silicon nitride or silicon oxynitride may be deposited on interior surfaces of the process chamber without a gettering layer, to thereby substantially prevent outdiffusion of underlying moisture and impurities during subsequent deposition of films onto the wafers to be processed.

    摘要: A method for conditioning a plasma etch chamber is presented. A plasma etch chamber is provided, which preferably includes a chuck for supporting a topography. A conditioning process may be performed in the etch chamber. The conditioning process preferably includes positioning a cover topography on or above the chuck. A conditioning feed gas containing (hydro)halocarbons may be introduced into the chamber. A conditioning plasma may be generated from the conditioning feed gas for a conditioning time. Immediately after generating the conditioning plasma is complete, the overall thickness of the cover topography is preferably at least as great as immediately before generating the conditioning plasma. By performing a conditioning process in such a manner, the total cost and complexity of the conditioning process may be reduced.
