  • Publication number: 20230411193
    Abstract: When there is an interruption in power to an area of an integrated circuit manufacturing facility, product may be stranded in a vehicle mounted to an automated material handling system. An automated rescue vehicle can be deployed to retrieve the stranded vehicle so that a payload carried by that vehicle can be recovered and processing can resume. The rescue vehicle can carry a battery payload. The battery payload provides backup power while the rescue operation is performed. With such an automated system, no human intervention is needed to recover product during a power outage. In addition to improving wafer throughput during the power outage, such a rescue operation may prevent quality degradation for time-critical sequences of processing operations.
