Abstract:
A system for separately handling different size FOUPs includes an end effector having a surface thereon for supporting a FOUP. The end effector and surface is configured to support different size FOUPs. A fixture or means for engaging and maintaining a FOUP, of different size FOUPs, included to position and maintain each of a different size FOUP on the end effector during transport thereof. A shelf is configured to receive each of said different size FOUPs. The end effector is thus capable of transporting either a first size FOUP or a second, smaller size FOUP.
Abstract:
Systems, machines, and methods for monitoring wafer handling are disclosed herein. A system for monitoring wafer handling includes a sensor and a controller. The sensor is capable of being secured to an assembled wafer handling machine. The controller is in electronic communication with the sensor and includes control logic. The control logic is configured to store a reference output of the sensor when the wafer handling machine is aligned and is configured to generate an indication signal when a difference between the reference output and a current output of the sensor exceeds a threshold.
