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.
