Abstract: A cleaning module for cleaning a wafer comprises a wafer gripping device configured to support a wafer in a vertical orientation and comprises a catch cup and a gripper assembly. The catch cup comprises a wall that has an annular inner surface that defines a processing region and has an angled portion that is symmetric about a central axis of the wafer gripping device. The gripper assembly comprises a first plate assembly, a second plate assembly, a plurality of gripping pin, and a plurality of loading pin. The gripping pins are configured to grip a wafer during a cleaning process and the loading pins are configured to grip the wafer during a loading and unloading process. The cleaning module further comprises a sweep arm coupled to a nozzle mechanism configured to deliver liquids to the front and back side of the wafer.
