    摘要: A slotted conical (non-flat) spring washer with an encircling ring provides improved spring washer performance. A split or slotted conical spring washer is encircled by a retaining ring that prevents the ends of the washer adjacent to the slot from expanding as the washer is compressed. The ends of the washer on both sides of the slot move to prevent the washer material from exceeding its yield strength. The ring restricts the radial movement of said outside diameter of the washer strip away from a center axis of the washer bore. The ring can be a counter bore in a member to be clamped, a retaining washer having an outside annular washer to act as the ring, or can be integral with the spring washer such that the slot appears not to pass completely through the washer strip.This slotted conical spring washer greatly increases the elastic spring travel available during repeated clamping cycles and during movement of clamped members due to differences in rates of thermal expansion and thermal gradients. A method for using the slotted spring washer fastening system invention assures electrical conductance and/or fluid vessel integrity under high temperatures and thermal gradients and when different materials are used in the clamped and clamping members.

    摘要: The present invention comprises an apparatus and method for centering a substrate in a process chamber. In one embodiment, the apparatus comprises a substrate support having a support surface adapted to receive the placement of a substrate and a reference axis substantially perpendicular to the support surface, and a plurality of centering members extending above the support surface. Each centering member is biased into a first position and is movable to a second position by interacting with an opposing member. A movement between the first position and the second position thereby causes each centering member to releasably engage with a peripheral edge of the substrate to push the substrate in a direction toward the reference axis.

    摘要: Non-bonded ceramic protection is provided for metal surfaces in a plasma processing chamber, particularly heated metal electrode surfaces, in a plasma processing chamber, to prevent or inhibit attack of the heated metal surfaces by chemically aggressive species generated in the plasma during processing of materials, without bonding the ceramic material to the metal surface. In accordance with the invention the ceramic protection material comprises a thin cover material which is fitted closely, but not bonded, to the heated metal. This form of ceramic protection is particularly useful for protecting the surfaces of glow discharge electrodes and gas distribution apparatus in plasma process chambers used for processing semiconductor substrates to form integrated circuit structures. The particular ceramic material used to provide the desired protection from the gaseous species generated by the plasma are selected from the group consisting of aluminum nitride, crystalline aluminum oxide, magnesium fluoride, and sintered aluminum oxide.

    摘要: A substrate heater assembly for supporting a substrate of a predetermined standardized diameter during processing is provided. In one embodiment, the substrate heater assembly includes a body having an upper surface, a lower surface and an embedded heating element. A substrate support surface is formed in the upper surface of the body and defines a portion of a substrate receiving pocket. An annular wall is oriented perpendicular to the upper surface and has a length of at least one half a thickness of the substrate. The wall bounds an outer perimeter of the substrate receiving pocket and has a diameter less than about 0.5 mm greater than the predetermined substrate diameter.
