Abstract: A steering apparatus and method is implemented that allows high speed, clean, particle-free transport of a semiconductor wafer or lithographic reticle on a transport vehicle at various positions on the vehicle track, especially when entering and exiting turns. Three computer-controlled electro-magnets are mounted at the left, center, and right side of a front steering truck, and are energized to attract strategically placed permanent magnet material mounted on a side of the track where the vehicle enters or exits a turn. The transport vehicle can be levitated by an air cushion or travel on wheels, and controlled by electromotive or electromagnetic forces about the track. Using the steering electro-magnets as a LVDT, a computer processor monitors the location of the transport vehicle about the track.

Abstract: Chemical vapor deposition methods of forming titanium silicide including layers on substrates are disclosed. TiCl4 and at least one silane are first fed to the chamber at or above a first volumetric ratio of TiCl4 to silane for a first period of time. The ratio is sufficiently high to avoid measurable deposition of titanium silicide on the substrate. Alternately, no measurable silane is fed to the chamber for a first period of time. Regardless, after the first period, TiCl4 and at least one silane are fed to the chamber at or below a second volumetric ratio of TiCl4 to silane for a second period of time. If at least one silane was fed during the first period of time, the second volumetric ratio is lower than the first volumetric ratio. Regardless, the second feeding is effective to plasma enhance chemical vapor deposit a titanium silicide including layer on the substrate.

Abstract: A trap device including at least one substance delivery element for introducing a substance therein is disclosed. The delivered substance may influence the nature of deposits that have formed within the trap device, may influence the formation of deposits within the trap device, or may cause a precipitate to form. Deposit interaction elements may be employed to influence the distribution or redistribution of deposits within the trap device. Deposit interaction elements may effect thermal conditions, introduce substances, or physically interact with deposits within the trap device. Further, a storage region within the trap device may be used to accumulate deposits. In one embodiment, a substantially continuous path through the trap device may be maintained or preserved so that deposits form within the trap device except substantially along the path. The present invention also encompasses a method of operation of a trap device as well as a system incorporating same.

Abstract: Communication between a controller and a set of automated vehicles in a manufacturing facility is improved by use of a closed-loop control system that operates on a real-time interrupt basis in which autonomous carriers report their location, sensed from reference markers along a track, the reference markers being referenced to an absolute grid in space, to a central controller or to one of a set of zone controllers that monitor the location of nearby vehicles that ordinarily use a token-passing system to avoid collisions, but which controllers can intervene to prevent one vehicle from blocking or interfering with another.

Abstract: Methods for passivating exposed surfaces within an apparatus for depositing thin films on a substrate are disclosed. Interior surfaces of a deposition chamber and conduits in communication therewith are passivated to prevent reactants used in a deposition process and reaction products from adsorbing or chemisorbing to the interior surfaces. The surfaces may be passivated for this purpose by surface treatments, lining, temperature regulation, or combinations thereof. A method for determining a temperature or temperature range at which to maintain a surface to minimize accumulation of reactants and reaction products is also disclosed. A deposition apparatus with passivated surfaces within the deposition chamber and gas flow paths is also disclosed.

Abstract: A semiconductor substrate processor includes a substrate transfer chamber and a plurality of substrate processing chambers connected therewith. An interfacial structure is received between at least one of the processing chambers and the transfer chamber. The interfacial structure includes a substantially non-metallic, thermally insulative mass of material interposed between the one processing chamber and the transfer chamber. The mass is of sufficient volume to effectively reduce heat transfer from the processing chamber to the transfer chamber than would otherwise occur in the absence of said mass of material. An interfacial structure includes a body having a substrate passageway extending therethrough. The passageway includes walls at least a portion of which are substantially metallic. The body includes material peripheral of the walls which is substantially non-metallic and thermally insulative. The substantially non-metallic material has mounting openings extending at least partially therein.

Abstract: A chemical vapor deposition chamber has a vacuum exhaust line extending therefrom. Material is deposited over a first plurality of substrates within the deposition chamber under conditions effective to deposit effluent product over internal walls of the vacuum exhaust line. At least a portion of the vacuum exhaust line is isolated from the deposition chamber. While isolating, a cleaning fluid is flowed to the vacuum exhaust line effective to at least reduce thickness of the effluent product over the internal walls within the vacuum exhaust line from what it was prior to initiating said flowing. After said flowing, the portion of the vacuum exhaust line, and the deposition chamber are provided in fluid communication with one another and material is deposited over a second plurality of substrates within the deposition chamber under conditions effective to deposit effluent product over internal walls of the vacuum exhaust line.

Abstract: The invention includes a method of forming a layer on a semiconductor substrate that is provided within a reaction chamber. The chamber has at least two inlet ports that terminate in openings. A first material is flowed into the reaction chamber through the opening of a first of the inlet ports. At least a portion of the first material is deposited onto the substrate. The reaction chamber is purged by flowing an inert material into the reaction chamber through the opening of a second of the inlet ports. The inert material passes from the opening and through a distribution head that is positioned within the reaction chamber between the first and second openings. A second material can then be flowed into the chamber through an opening in a third inlet port and deposited onto the substrate. The invention also includes a chemical vapor deposition apparatus.

Abstract: A hoisting method and device for use in an overhead traveling carriage system are disclosed. The hoisting device includes an engager for engaging an object and a linearly expandable structure coupling the engager to a base point. A single hoist member is coupled at a first end to the engager and at a second end to a motorized drum, coupled to the base point, for substantially vertically retracting and extending the single member. Since a single hoist member is used, the amount of precision machining and technician training are reduced. The linearly expandable structure includes at least one lazy-tong linkage or a telescoping structure, which provides sway stability and compactness. The invention may also include a six-degree adjustment structure that may include a feedback system for use with the linearly expandable structure to provide increased accuracy.
