  • Publication number: 20070144439
    Abstract: The present invention generally provides an apparatus and method for processing substrates using a multi-chamber processing system (e.g., a cluster tool) that is easily configurable, has an increased system throughput, increased system reliability, improved device yield performance, a more repeatable wafer processing history (or wafer history), and a reduced 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, and then certain portions of the photosensitive material are removed in a developing process completed in the cluster tool.

  • Patent number: 7234584
    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.

  • Patent number: 7230702
    Abstract: A movable portion of a substrate carrier handler is extended into a transport path along which a substrate carrier transport system transports a substrate carrier, respective kinematic coupling events are detected between corresponding interface elements of the movable portion and the substrate carrier, respective signals are generated in response thereto, and an alignment offset between the substrate carrier and the substrate carrier transport system is determined based on the signals. A movable portion matches an elevation, position, and/or a speed/velocity of a substrate carrier moving along the transport path. Sensors for detecting kinematic coupling and generating signals in response thereto are provided on the movable portion. An end effector includes a support with interface elements and sensors for detecting kinematic coupling and generating respective signals.

  • Publication number: 20070108019
    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.

  • Patent number: 7218983
    Abstract: In at least one aspect, the invention provides an electronic device fabrication facility (Fab) that uses small lot carriers that may be transparently integrated into an existing Fab that uses large lot carriers. A manufacturing execution system (MES) may interact with the inventive small lot Fab as if the small lot Fab is any other Fab component in an existing large lot Fab without requiring knowledge of how to control small lot Fab components (e.g., beyond specifying a processing recipe). A small lot Fab according to the present invention may encapsulate the small lot Fab's internal use of small lot components and present itself to a large lot Fab's MES as if the small lot Fab is a component that uses large lot carriers.

  • Patent number: 7168553
    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. A balancing mass is coupled directly or indirectly to a frame on which the substrate carrier handler is mounted and is adapted to accelerate in a direction opposite to the direction of end effector acceleration, as the end effector accelerates. Thus, inertial loads may be substantially balanced, and frame vibration reduced, despite potentially high rates of acceleration. Numerous other aspects are provided.
