Abstract:
A go no-go gauge and method for verifying whether a process kit part used within a plasma chamber of a plasma processing tool has accumulated excessive wear or deposits. The gauge includes a component for verifying whether a dimension of a process kit part feature violates a prescribed size tolerance, the violation indicating that the process kit part has accumulated excessive wear or deposits.
Abstract:
A gas delivery system for a plasma apparatus including a first plate having a gas inlet, and a second plate having a plurality of holes. The second plate is coupled to the first plate and spaced apart from the second to form a plenum chamber. A baffle honeycomb core is disposed between the first plate and the second plate in side the plenum chamber. The honeycomb core can be comprised of one or more spaced apart honeycomb panels. A surface of one of the honeycomb panels or a surface of the first panel can be contoured to control the pressure distribution of a gas in the plenum chamber. The gas delivery assembly for a plasma apparatus also includes a first plate having a gas inlet and a second plate coupled to the first plate to form a plenum chamber therebetween. The second plate includes a gas injection plate having a plurality of holes. The gas injection plate has a contoured surface such that a length of each of the plurality of holes varies depending on location of the holes on the contoured surface.
Abstract:
A multi-panel display has at least two foamboard panels with a foam core and outer layers, and a web hinge connecting adjacent foamboard panels. The web hinge is secured to the respective edges of the adjacent panels with a web extending therebetween, the web offset from the outer layers of the panels to adapt the panels for bidirectional folding movement. One web hinge is a strip of flexible sheet material having marginal edges, received in slits in the foam cores of adjacent panels. The edges may be secured at time of manufacture or inserted by the user to connect selected panels. The web hinges may have an I-shape secured to edges of adjacent panels, or may have U-shaped flanges embracing edges of adjacent panels, with a web connecting the flanges.
Abstract:
A plasma reactor includes a plasma processing chamber which can, for example, play the role of a vacuum chamber and an electrode disposed inside the plasma processing chamber. The plasma reactor further includes a plasma control structure imbedded entirely within the electrode. The plasma control structure is configured and arranged to alter characteristics of a plasma generated inside the processing chamber.
Abstract:
A device and method for controlling the temperature of a plasma chamber inside wall or other surfaces exposed to the plasma by a plurality of temperature control systems. A plasma process within the plasma chamber can be controlled by independently controlling the temperature of segments of the wall or other surfaces.
Abstract:
A viewing port for a processing chamber is provided that includes a viewing window cleaning apparatus, a viewing window, and a mounting, where the viewing window cleaning apparatus is coupled to the mounting and disposed between the viewing window and the process chamber, and is configured to form a cleaning plasma in a cleaning plasma region of the mounting. In addition, the mounting can be configured to reduce a number of by-products from a process chamber on the viewing window by preventing them from propagating to the window.
Abstract:
A plasma processing system and a method for processing a substrate with a plasma processing system. An aspect of the invention provides a plasma processing system that comprises a chamber, including a processing region and an opening, a plasma generating system, constructed and arranged to produce a plasma during a plasma process in the processing region, a chuck, constructed and arranged to support a substrate within the chamber in the processing region, a ring member arranged in the chamber and a moving assembly, constructed and arranged to move the ring member, wherein the ring member is mounted on a periphery of the chuck such that when the substrate is being processed the ring member seals the opening.
Abstract:
A multi-stop mechanism for providing multiple stop positions between first and second objects that are movable into and out of contact with one another. The multi-stop mechanism of the present invention includes a housing which secures the multi stop mechanism to the first object and/or the second object, a rotatble shaft rotatably mounted to the housing, and plurality of stops located on the rotatable shaft. When the shaft is rotated within the housing, the stops are rotated to different positions relative to the housing. As such, the rotatable shaft positions one of the stops to contact the first or second object that the multi-stop mechanism is not attached to.
Abstract:
A plasma reactor including a process chamber, a holding structure constructed arranged to hold a plasma source assembly and a support structure constructed and arranged to support a chuck assembly. The holding structure at least partially constitutes a wall of said vacuum chamber. The support structure supporting or holding the chuck assembly can be coupled to a lift mechanism which can raise or lower the chuck assembly relative to the plasma source assembly. The lift mechanism can be disposed above or below the process chamber.
