Abstract:
A hand-held, cubic, transparent game system containing a cubiform array of individual LEDs arranged as a cubic matrix of rows and columns, an inclinometer, sound chip and speaker and a timer. Electronic control circuitry including a game-programmed processor is connected between the inclinometer and the LED array to control visible operating states of individual lamps in response to output signals from the inclinometer, according to rules of a game program. Sequential LEDs in a direction of inclination are momentarily flashed to define a traveling cursor. Turning the housing through 90 degrees transfers cursor between a row and a column.
Abstract:
A plasma reactor sub-assembly includes both an electrostatic shield and a process tube. Optionally, the electrostatic shield and the process tube are connected. Alternatively, they are configured to fit together without being physically connected. The sub-assembly may be manufactured using a process tube nested within the circumference of an electrostatic shield, an electrostatic shield patterned directly on a process tube using, for example, thin film deposition, or a process tube bonded or not bonded to an electrostatic shield made of a flexible, electrical film material.
Abstract:
A focus ring assembly, configured to be coupled to a substrate holder in a plasma processing system, comprises a focus ring having one or more wear indicators for determining the lifetime of the focus ring, wherein the coupling of the focus ring to the substrate holder facilitates auto-centering of the focus ring in the plasma processing system. For example, a centering ring mounted on the substrate holder can comprise a centering feature configured to couple with a mating feature on the focus ring.
Abstract:
An access assembly for a process chamber, including a wall segment constructed and arranged to access the process chamber, a mounting assembly constructed and arranged to couple the wall segment to the process chamber, and a sealing plate mounted to the process chamber. The sealing plate is constructed and arranged to isolate the wall segment from a volume inside the process chamber.
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 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.
