    • The presence of a workpiece on an end effector of a vacuum robotic handler is detecting using any of a number of non-contact techniques in which some or all of the detection hardware is positioned outside a vacuum chamber that encloses the vacuum robotic handler. Various deployments include laser beam breaking, analysis of radar reflection signals, or analysis of radio frequency identification tag signatures. By providing non-physical couplings between hardware inside and outside of a vacuum environment, integrity of the vacuum is improved. These non-contact techniques are further adapted as described herein to multi-wafer and multi-end effector environments so that independent detection of multiple wafers (e.g., for each end effector) can be performed.
    • 在真空机器人处理器的末端执行器上存在工件是使用许多非接触技术中的任何一种来检测的,其中一些或全部检测硬件位于包围真空机器人处理器的真空室外部。 各种部署包括激光束破碎,雷达反射信号分析或射频识别标签签名分析。 通过在真空环境内部和外部的硬件之间提供非物理耦合,提高了真空的完整性。 这些非接触技术如本文所述进一步适应于多晶片和多端效应器环境,使得可以执行多个晶片(例如,对于每个末端执行器)的独立检测。

    • A system of moving magnets for sealing a container may include a plurality of moveable magnets disposed near a perimeter of a container door and a rotatable linkage hub positioned within the perimeter of the container door. In addition, the system may include a plurality of control linkages connecting each of the plurality of moveable magnets to the linkage hub so that rotating the linkage hub causes the control linkages to move the moveable magnets between a sealed position and an open position. Alternatively, the moveable magnets may be connected to each other by a magnet positioning mechanism to physically move the magnets along a path near the perimeter. A plurality of static magnets may be disposed near an opening sized to receive the container door and positioned to form a magnetic seal with the moveable magnets when the moveable magnets are positioned at the sealed position.
