Abstract:
A storage system for items such as substrate carriers includes at least one stocker including a plurality of storage areas each adapted to store at least one storage device. At least one movable support is arranged on the at least one stocker. A control controls movement of the at least one movable support at least between a first position wherein the at least one movable support receives the at least one storage device outside one of the storage areas and a second position wherein the at least one movable support is arranged substantially within the one of the storage areas.
Abstract:
A storage buffer system for an automated material handling system (AMHS) includes a retractable buffer device disposed in proximity to a processing tool, the retractable buffer device having an extended position disposed directly below an overhead transport (OHT) vehicle path. The retractable buffer device further includes a retracted position that is removed from a process aisle space. In the extended position, the retractable buffer device is configured to facilitate loading and unloading of product therein without the use of lateral motion capability of an OHT vehicle.
Abstract:
A carrier for the masks used in Electron Projection Lithography, or other workpieces used in nanotechnology fields, comprises a rectangular frame having a set of four electrostatic chucks in the top surface for holding the mask above a central aperture that has an electron absorber on the bottom for suppressing backscattering; the frame being supported by a bottom carrier that grips the frame with a set of flexures flexible in the z-direction, stiff in an azimuthal direction and flexible in a radial direction.
Abstract:
A system for supporting and adjusting the position of an object in a vacuum includes inner and outer support rings that are connected by flexible mounts that are compliant along one axis and stiff along other axes, and drivers extending through the wall of the vacuum chamber that move the supports independently along their respective axes. At least the inner support is clamped after adjustment by a clamp that exerts a strong clamping pressure while exerting transverse force only less than a threshold selected to avoid motion after adjustment.
Abstract:
A overhead transport service vehicle system includes a carriage frame structured and arranged to carry a user. A hoisting mechanism utilizes at least one lifting device for lifting and lowering the carriage frame and at least one moving device for causing movement of the hoisting mechanism along one of a track or rail. A control controls at least one of the at least one lifting device and the at least one moving device.

Abstract:
The present invention relates to a method and apparatus of fabricating electromagnetic coil vanes. The method involves photolithographically exposing high resolution, dense wire patterns in a flash coat of copper, on both sides of a ceramic vane substrate. The substrate can be pre-drilled with a through hole to connect the two copper coil patterns. Additional copper is then deposited on both high resolution patterns and in the through hole by plating until the desired thickness is obtained. A firing operation is then performed that eutectically bonds the copper to the ceramic.
Abstract:
A beam-limiting aperture truncates selected portions of a charged particle beam illuminating portions such as subfields of a patterned reticle of a charged particle beam projection lithography tool and then projects a pattern of charged particles onto a target in a charged particle beam lithography tool. The respective portions of the reticle are patterned in accordance with respective portions of an integrated circuit or other desired pattern and may have differing transmissivities; altering beam current at the target even when source beam current remains substantially constant. The portion of the beam which is truncated, thus altering the particle trajectory semi-angle and numerical aperture of the tool is controlled in accordance with the transmissivity of the reticle portion to enhance resolution to near optimal limits.
Abstract:
An energy efficient air flow control system includes exhaust devices of a building air flow management system. Each of the exhaust devices includes a controller for controlling functions of its respective exhaust device. A first sensor is coupled to each of the exhaust devices and respective controllers. A computer is coupled to the exhaust devices via respective controllers. A second sensor determines a fan speed of a supply air fan, and the second sensor is coupled to the computer. Logic executable by the computer receives user-selected settings for controlling operation of the exhaust devices, collects data from the controllers via corresponding first sensors and from the second sensors, applies the data to the settings, and modifies operation of the system via a controller of at least one of the exhaust devices when, in response to applying the data, it is determined that a condition defined in the settings is met.
