    • Wet processing equipment automatically and rapidly unloads unit lots of semiconductor devices at an input port unit without any intervention of an operator in the event of an emergency, and thereby prevents unforeseen operational problems. The semiconductor wet processing equipment includes an emergency output port unit integral with the input port unit. The emergency output port unit will transfer lots directly from the loading position established by the input port unit and set the lots at an emergency unloading position when a predetermined condition occurs in the wet processing equipment. When such a condition occurs, a process canceling command is input from a host computer. If the process canceling command is input, the controller determines whether the lot is in a standby state at the loading position. If the lot is in the standby state, the process canceling command is downloaded into the processing equipment. Then a determination is made as to whether the lot has been unloaded from the input port unit onto the emergency output port unit. If the lot has been unloaded from the input port unit onto the emergency output port unit, an AGV operating command is downloaded into an AGV server.
    • 湿处理设备在输入端口单元处自动且快速地卸载单元批量的半导体器件,而在紧急情况下无需操作人员的任何干预,从而防止不可预见的操作问题。 半导体湿式处理设备包括与输入端口单元集成的紧急输出端口单元。 紧急输出端口单元将直接从输入端口单元建立的装载位置传送批量,并在湿式处理设备中发生预定条件时将批量设置在紧急卸载位置。 当发生这种情况时,从主计算机输入处理取消命令。 如果输入过程取消命令,则控制器确定批次是否在加载位置处于待机状态。 如果批次处于待机状态,则将处理取消命令下载到处理设备中。 然后确定批次是否从输入端口单元卸载到紧急输出端口单元上。 如果批次已从输入端口单元卸载到紧急输出端口单元上,则AGV操作命令将下载到AGV服务器中。
