    • A safety system for an overhead transport (OHT) vehicle. In one embodiment, the safety system may include a pair of safety panels provided on opposite sides of the load and unload ports on a tool or stocker. An overhead sensor is provided on the OHT and is operably connected to a light curtain on the tool. In the event that the overhead sensor detects an obstruction in the travel path of the OHT during loading of a pod or cassette into the tool or stocker, the light curtain transmits an emergency stop signal to the tool or stocker controller, which terminates further loading operation of the OHT. In another embodiment, the light curtain assumes the look-down sensing function of the overhead sensor in the event that tool components interfere with the look-down function of the overhead sensor.
    • 架空运输(OHT)车辆的安全系统。 在一个实施例中,安全系统可以包括设置在工具或储料器上的负载和卸载端口的相对侧上的一对安全面板。 在OHT上设置一个顶置式传感器,并可操作地连接到工具上的光幕。 如果架空传感器检测到将货舱或卡盘装载到工具或储料架内的OHT的行进路径中的障碍物,则光幕将紧急停止信号传送到工具或储料柜控制器,从而终止进一步的装载操作 的OHT。 在另一个实施例中,在工具部件干扰架空传感器的俯视功能的情况下,光幕采用架空传感器的俯视感测功能。

    • The present invention discloses a method for controlling lots' dispatch of tool groups, and all the lots can be transferred to correct places for further processing. The lots are transferred to the storage places of the tool when there is only a single tool for the next process. A decision step is performed for deciding whether the storage places of the next tool group and the next-next tool group overlap when the next process contains a tool group. If there are overlapped storage places, then the lots will be moved to the overlapped storage place having minimum loading. When there is no overlapped storage place, the lots will be dispatched to the storage place having minimum loading among the next tool group. All the lots can be processed with at minimum moving steps, and all the tools perform their processes under balance loading whenever the productions increase or decrease.
    • 本发明公开了一种用于控制工具组批量分配的方法,所有批次都可以转移到正确的位置进行进一步处理。 当只有一个工具用于下一个过程时,批次将被转移到工具的存储位置。 执行决定步骤,用于当下一个进程包含工具组时,决定下一个工具组和下一个下一个工具组的存储位置是否重叠。 如果存在重叠的存放位置,则批次将被移动到具有最小负载的重叠存储位置。 当没有重叠的存放位置时,批次将被分派到下一个工具组中具有最小装载量的存储位置。 所有的批次可以以最小的移动步骤进行处理,并且所有工具在生产增加或减少的情况下均衡加载。

    • A method for aligning a loadport of a process machine to an overhead hoist transport (OHT) system which can be carried out by first providing an OHT rail overhanging a cleanroom floor; setting a reference point in the cleanroom in proximity to the OHT rail; marking on the cleanroom floor boundary reference lines for each row of process machines based on the reference point; positioning a process machine on the cleanroom floor with a boundary line of the machine aligned to the boundary reference line; mounting a loadport onto the process machine; and fine tuning a center line of the loadport to a reference line on the floor that is 200 mm apart from and parallel to the boundary reference line.
