  • Patent number: 5846332
    Abstract: A substrate processing chamber, particularly a chemical vapor deposition (CVD) chamber used both for thermal deposition of a conductive material and a subsequently performed plasma process. The invention reduces thermal deposition of the conductive material on peripheral portions of the pedestal supporting a wafer and in a pumping channel exhausting the chamber. A peripheral ring placed on the pedestal, preferably also used to center the wafer, is thermally isolated from the pedestal so that its temperature is kept substantially lower than that of the wafer. Despite its thermal isolation, the peripheral ring is electrically connected to the pedestal to prevent arcing. The pumping channel is lined with various elements, some of which are electrically floating and which are designed so that conductive material deposited on these elements do not deleteriously affect a plasma generated for processing the wafer.

  • Patent number: 5804507
    Abstract: An apparatus for polishing semiconductor wafers and other workpieces that includes a polishing pads mounted on respective platens at multiple polishing stations. Multiple wafer heads, at least one greater in number than the number of polishing stations, can be loaded with individual wafers. The wafer heads are suspended from a carousel, which provides circumferential positioning of the heads relative to the polishing pads, and the wafer heads oscillate radially as supported by the carousel to sweep linearly across the respective pads in radial directions with respect to the rotatable carousel. Each polishing station includes a pad conditioner to recondition the polishing pad so that it retains a high polishing rate. Washing stations may be disposed between polishing stations and between the polishing stations and a transfer and washing station to wash the wafer as the carousel moves. A transfer and washing station is disposed similarly to the polishing pads.

  • Patent number: 5773100
    Abstract: An inlet gas manifold for a vacuum deposition chamber incorporates inlet apertures which increase in diameter or cross-section transverse to the direction of gas flow. The aperture configuration increases the dissociation gases such as nitrogen and, thus increases the rate of silicon nitride deposition provided by nitrogen gas chemistry, without requiring the use of reactants such as ammonia. While one could use ammonia in the deposition gas chemistry if desired, the process provides the option of completely eliminating ammonia. The inlet manifold containing the increasing-diameter gas inlet holes provides enhanced control of the process and the deposited film.

  • Patent number: 5705225
    Abstract: Anodized aluminum coatings employed in semiconductor processing equipment are treated to reduce their sensitivity to halogenated species. The pores of the aluminum oxide surface can be filled either by a metal, such as magnesium or aluminum, forming the corresponding metal oxide that is resistant to reaction with halogens, or by filling the pores with a getter for halogens, such as hydrogen ions. The hydrogen ions adsorbed on the surface of the aluminum oxide react with halogens to form volatile hydrogen halides that can be pumped away in the exhaust system of the semiconductor processing chambers, thereby preventing or reducing reaction of the underlying aluminum oxide with the halogens.
