Abstract:
A plasma processing system includes a chamber containing a plasma processing region and a chuck constructed and arranged to support a substrate within the chamber in the processing region. The plasma processing system further includes at least one gas injection passage in communication with the chamber and configured to facilitate removal of particles from the chamber by passing purge gas therethrough. In one embodiment, the plasma processing system can include an electrode configured to attract or repel particles in the chamber by electrostatic force when the electrode is biased with DC or RF power. A method of processing a substrate in a plasma processing system includes removing particles in a chamber of the plasma processing system by supplying purge gas through at least one gas injection passage in communication with the chamber.
Abstract:
An electrode plate, configured to be coupled to an electrode in a plasma processing system, comprises a plurality of gas injection holes configured to receive gas injection devices. The electrode plate comprises three or more mounting holes, wherein the electrode plate is configured to be coupled with an electrode in the plasma processing system by aligning and coupling the three or more mounting holes with three or more mounting screws attached to the electrode.
Abstract:
A baffle plate assembly, configured to be coupled to a substrate holder in a plasma processing system, comprises a baffle plate having one or more openings to permit the passage of gas there through, wherein the coupling of the baffle plate to the substrate holder facilitates auto-centering of the baffle plate in the plasma processing system. For example, a centering ring mounted in the substrate holder can comprise a centering feature configured to couple with a mating feature on the baffle plate. After initial assembly of the plasma processing system, the baffle plate can be replaced and centered within the plasma processing system without disassembly and re-assembly of the substrate holder.
Abstract:
A thermally zoned substrate holder including a substantially cylindrical base having top and bottom surfaces configured to support a substrate. A plurality of temperature control elements are disposed within the base. An insulator thermally separates the temperature control elements. The insulator is made from an insulting material having a lower coefficient of thermal conductivity than the base (e.g., a gas- or vacuum-filled chamber).
Abstract:
An apparatus for monitoring film deposition on a chamber wall in a process chamber. The apparatus includes a surface acoustic wave device provided on the chamber wall. The surface acoustic wave device is actuated to achieve a resonance frequency, and the resonance frequency produced is detected to determine whether a critical thickness of film on the wall of the chamber has been achieved, where an amount of decrease in the resonance frequency is proportional to a thickness of film on the chamber wall. The process chamber is cleaned when the resonance frequency detected falls within a first predetermined range.
Abstract:
An entertainment device is configured to receive a limited range wireless signal from at least one other entertainment device when adjacently arranged in close physical proximity to at least one other entertainment device, and to responsively operate in a first mode or a second mode based on whether the other entertainment device is adjacent a first side or second side. In the first mode, the entertainment device initiates one or more wireless activation signals to control an audio/visual element of another entertainment device. In the second mode, the entertainment device receives wireless activation signals from another entertainment device to control activation of an audio/visual element of the receiving entertainment device. Each device is interchangeable between operation in the first mode of controlling at least one other entertainment device and the second mode of being controlled by another entertainment device based on position of one entertainment device relative to the other.
Abstract:
An aspect of the present invention provides a toy assembly system comprising a central compartment configured to house a plurality of toy bodies, each toy body having magnetic hubs arranged in an outer region of the body. The system can include outer compartments that house ferromagnetic outer components (e.g., ferromagnetic spheres) separate from the toy bodies and a release mechanism configured to release during a single operation a single toy body and a set of outer components, wherein the single toy body and the set of outer components self-assemble and automatically align. Another aspect provides a toy track system comprising a launch portion configured to magnetically retain the magnetic vehicle in a launch position, a release configured to release the vehicle from the launch position, and a track portion coupled to the launch portion and configured to guide the released vehicle along a predetermined path.
Abstract:
The present invention provides a disposable component for a plasma processing system, wherein the component includes a non-refractory ceramic fiber, refractory ceramic fiber, alumina, alumina-silica, or zirconia, or any combination of two or more thereof in the form of a rigid material, flexible material, paper, cloth, felt, mat, screen, sheet, tape, blanket, fiber, woven fiber, or nonwoven fiber, or any combination of two or more thereof.
Abstract:
A fastening component for fastening together a first component and a second component used in a plasma processing tool. The fastening component includes a first surface configured to be exposed to plasma processing performed in the plasma processing tool, and a second surface configured to contact the first component. Also included is a stem extending from the second surface and configured to at least partially protrude through the first component and the second component. The fastening component further includes a locking pin extending from at least one side of the stem and configured to contact the second component. The first surface, the second surface, the stem, and/or the locking pin are made of or coated with a material that is highly resistant to erosion resulting from plasma processing.
