The at least one storage unit may include a plurality of shelves or storage compartments for storing files, books, computer printouts and the like. A handle is mounted on an end of the at least one storage unit to facilitate the extension and retraction of the unit. The base frame assembly includes a stationary base frame and a movable carriage. The carriage further comprises a primary frame and an intermediate frame, which telescopically nest within the base frame when in a fully retracted position. Rollers are attached to the frame members of the intermediate frame and are configured to slidably engage channel members of the base frame and the primary frame. Retaining clips are provided to prevent extension of the primary and intermediate frames beyond a predetermined distance. A locking mechanism prevents the extension of more than one storage unit at a time. A drive system may be provided to assist in the extension and retraction of storage units.

    摘要: A web-based data analysis and tracking system and method for a medium to large organization. Metrics can be determined by asking pre-defined and special questions designed and modified by the facility or organization. The totality of answers to these questions represent a set of metrics that can be weighted and analyzed to produce comparisons with standard or chosen thresholds and/or industry standards. Compliance with best practices can be evaluated, and variances from best practices can be flagged and made visible. The present invention first assures that the organization has reliable data. Next, it analyzes this data to form comparisons and usable output. Finally, it presents the output in various graphical formats that can be used to base management decisions upon such as dashboards, graphs and textual output.

    摘要: A method and an apparatus for sorting between actual and perceived errors related to processing of semiconductor wafers. A plurality of semiconductor wafers are processed. Fault data relating to the processed semiconductor wafers is acquired. A trend associated with the fault data is determined. A determination is made whether the fault data relates to an actual fault associated with the semiconductor wafers or to a calibration error, based upon the trend. A component is notified of the calibration error in response to the determination that the fault data relates to the calibration error.

    摘要: A method for measuring defects includes receiving a defect characteristic measurement for each measurement site in a first subset of a plurality of measurement sites on a workpiece. A second subset of the plurality of measurement sites is defined. The size of the second subset is based on the defect characteristic measurements of the first subset of the plurality of measurement sites. A metrology tool is directed to measure the defect characteristic at each of the measurement site in the second subset responsive to the size of the second subset being greater than zero. A system includes a metrology tool and a controller. The metrology tool is configured to measure a defect characteristic at each of a first plurality of measurement sites on a workpiece. The controller is configured to compare the measured defect characteristics at the first plurality of measurement sites against a first predetermined threshold and direct the metrology tool to measure the defect characteristic at each of a second plurality of measurement sites on the workpiece responsive to the measured defect characteristics being greater than the first predetermined threshold.
