  • Publication number: 20070108020
    Abstract: A break-away mounting system for a continuous-motion, high-speed position conveyor system is disclosed. A support cradle may be suspended from a conveyor belt such that the support cradle maintains a fixed position and orientation relative to at least one point on the conveyor belt without inducing appreciable stress on the conveyor belt, the support cradle, or the coupling between the conveyor belt and the support cradle. The mount may include a leading rotatable bearing attached to the support cradle which may releasably engage a first key attached to the conveyor belt, the rotatable bearing adapted to accommodate rotational forces applied to the support cradle by the conveyor belt. The mount may also include a slide bearing attached to the support cradle which may releasably engage a second key attached to the conveyor belt, the slide bearing adapted to accommodate longitudinal forces applied to the support cradle by the conveyor belt.

  • Publication number: 20070059145
    Abstract: In a semiconductor fabrication facility, a conveyor transports substrate carriers. The substrate carriers are unloaded from the conveyor and loaded onto the conveyor without stopping the conveyor. A load and/or unload mechanism lifts the substrate carriers from the conveyor during unloading operations, while matching the horizontal speed of the conveyor. Similarly, during loading operations, the load/unload mechanism lowers a substrate carrier into engagement with the conveyor while matching the horizontal speed of the conveyor. Individual substrates, without carriers, may be similarly loaded and/or unloaded from a conveyor.

  • Publication number: 20070061042
    Abstract: In a first aspect, a substrate loading station is served by a conveyor which continuously transports substrate carriers. A substrate carrier handler that is part of the substrate loading station operates to exchange substrate carriers with the conveyor while the conveyor is in motion. A carrier exchange procedure may include moving an end effector of the substrate carrier handler at a velocity that substantially matches a velocity of the conveyor. Numerous other aspects are provided.

  • Publication number: 20070061031
    Abstract: A band to band transfer module according to the present invention may be used with a substrate carrier transport system, or other systems, to transfer substrate carriers (e.g., small lot substrate carriers) from one conveyor to another conveyor or between two points on the same conveyor. The transfers (e.g., pick and place) of the substrate carriers may be made between conveyors traveling at different speeds. Numerous other aspects and features are disclosed.

  • Publication number: 20060286300
    Abstract: Embodiments generally provide an apparatus and method for processing substrates using a multi-chamber processing system (e.g., a cluster tool) that has an increased system throughput, increased system reliability, substrates processed in the cluster tool have a more repeatable wafer history, and also the cluster tool has a smaller system footprint. In one embodiment, the cluster tool is adapted to perform a track lithography process in which a substrate is coated with a photosensitive material, is then transferred to a stepper/scanner, which exposes the photosensitive material to some form of radiation to form a pattern in the photosensitive material, which is then removed in a developing process completed in the cluster tool.
