Patents by Inventor Amitabh Puri

Amitabh Puri has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7603195
    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: 7603196
    Abstract: Methods and apparatus are provided for managing movement of small lots between processing tools within an electronic device manufacturing facility. In some embodiments, a number of priority lots to be processed is determined and an equivalent number of carrier storage locations are reserved at a substrate loading station of a processing tool. The number of reserved carrier storage locations are made available either by processing and advancing occupying non-priority lots and/or moving unprocessed occupying non-priority lots from the substrate loading station. Priority lots are then transferred to the reserved carrier storage locations. Other embodiments are provided.

  • Publication number: 20070276532
    Abstract: Systems, tools, and methods are provided in which a first signal is transmitted from a tool to a Fab indicating that all substrates to be processed have been removed from a specific carrier and that the specific carrier may be temporarily unloaded from a loadport of the tool. A second signal is transmitted from the tool to the Fab indicating that the specific carrier may be returned to the tool. While the carrier is unloaded from the tool, other carriers may be loaded on the vacated loadport. Numerous other features and aspects of the invention are disclosed.

  • Publication number: 20070276531
    Abstract: A carrier handler is provided that may be adapted to (1) accept transfer commands for carriers before the carriers arrive within the domain of the carrier handler; (2) accept termination commands that result in prior commands being cancelled or aborted independent of the state of the prior commands; (3) select queued commands for out-of-order execution to take advantage of earliest arriving transport system carrier supports suitable for use with the selected commands and/or based upon the anticipated time needed to execute the commands; (4) remove empty carriers from an associated tool to improve port availability; (5) continue to operate even after transfers involving storage locations fail by removing the failed locations from a usable locations list; (6) verify the integrity of carrier and transfer destination status data with sensors prior to attempting a transfer; and (7) calibrate carrier handoffs with a transport system using a calibration carrier equipped with sensors.

  • 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.
