  • Publication number: 20040149210
    Abstract: A method and system for reducing the cost of a vacuum processing system by utilizing separately fabricated parts for the walls and the tops and bottoms of chambers. Walls are formed from cylinders (e.g., aluminum tubing or rolled ring forgings), and plates are then hermetically sealed to the top and bottom of the cylinder. Fasteners (and the vacuum inside the chamber) clamp the plates to the cylinder.

  • Publication number: 20040149389
    Abstract: This invention relates to a plasma processing system. A common problem in the manufacture of semiconductors is the maintenance of a constant fluid flow throughout the chamber in which the semiconductors are being etched. The focus ring described herein helps control fluid flow such that all (or substantially all) of a substrate (e.g., semiconductor) surface is exposed to a constant flow of plasma throughout the etching process. An even fluid flow is maintained by adjusting the configuration of a focus ring, a pumping baffle, or a focus ring working with an auxiliary focus ring with respect to the semiconductor surface. By manipulating the position of the focus ring, pumping baffle, and auxiliary focus ring, fluid flow over the surface of the semiconductor can be increased, decreased, or kept stagnant.

  • Publication number: 20040017049
    Abstract: A sealing apparatus includes a sealing arrangement and a groove in a base. The sealing arrangement may comprise an o-ring and a grounding gasket where both the o-ring and the grounding gasket partially protrude in a longitudinal direction from the groove. Thus, the grounding gasket, which is equipped with ends that can be pulled out of the groove, can be removed from the groove by a pulling force. This leaves the o-ring accessible for removal or maintenance at a much lower cost in terms of manufacturing and operational costs. The sealing arrangement may also include inner and outer o-rings which seal a fluid flow from the atmosphere.
