Abstract: A combination of a FOUP (front opening unified pod) system and a reticle system utilized for the transport of wafers and a reticle system, the latter of which are used for transporting reticles from a first fabrication site to a further site at another location, and which provides for a unified system enabling the automated and trackable delivery of the reticles between these sites. Provided is a modified FOUP base structure, which is adapted to retain a reticle and to be able to employ existing equipment in a fabrication site which only necessitates a minimal modification of the equipment in order to render the latter universally adaptable to the combination of the systems.

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 method of transporting workpieces to tools in an automated transportation system dispatches an automated transport vehicle containing workpieces from a first location such as a first loadport to a tool when the automated transport vehicle is available for dispatch and loaded with the workpieces, irrespective of whether the tool is available to receive the workpieces. Next, the method directs the automated transport vehicle to travel from the first loadport, along an interbay loop to an intrabay loop. The intrabay loop comprises a transport route around the tool and the interbay loop comprises a transport route that connects the loadport to a plurality of intrabay loops. The method directs the automated transport vehicle to travel along the interbay loop and stop at a tool loadport of the tool only if the tool is available to work on the workpieces.

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 clamping flexure for use in a vacuum employs a spring-loaded shaft that pulls an object being supported against a support piece, including a mechanism, passing through the vacuum vessel, for releasing the spring tension during adjustment, the shaft being sufficiently compliant that restoring force after adjustment is less than a threshold value so that displacement of the shaft does not impress a force on the object being supported that returns it toward its position before adjustment.

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 method and apparatus for clamping a semiconductor mask to a carrier device is taught. The apparatus is comprised of a base member to which is attached an elongated spring. Both the base and the spring have affixed to them a means for compressively contacting the mask surface when the mask is put in place. In the preferred embodiment, that contact means is made of sapphire shaped in the form of a dome. The clamp further includes an adjustment screw that can be used to adjust the height of the contact means affixed to the base member. In this manner, the surface of the mask can be adjusted so that it is planarized to the right orientation relative to an e-Beam or laser source that will be used to scribe a pattern on the mask. Finally, the clamp includes electrical contacts, and the materials out of which the clamp is made are deliberately selected, so that no electrical or magnetic forces can build up on the clamp or the wafer that might adversely affect the scribing process.

Abstract: The present invention relates to a method of fabricating electromagnetic coil vanes. The method utilizes laser machining to provide high resolution, dense coil wire patterns on both sides of a ceramic vane substrate. A firing operation is first performed that eutectically bonds the copper to the ceramic. Laser machining is then used to produce a coil pattern in the copper. The substrate is drilled to provide a through hole which, when filled or partially filled with a conducting material, forms an electrical connection between the two coil patterns.
