Systems and methods for wafer grounding and wafer grounding location adjustment are disclosed. A first method may include receiving a first value of an electric characteristic associated with the wafer being grounded by an electric signal; determining a first control parameter using at least the first value; and controlling a characteristic of the electric signal using the first control parameter and the first value. A second method for adjusting a grounding location for a wafer may include terminating an electric connection between the wafer and at least one grounding pin in contact the wafer; adjusting a relative position between the wafer and the grounding pin; and restoring the electric connection between the grounding pin and the wafer. A third method may include causing a grounding pin to penetrate through a coating on the wafer by impact; and establishing an electrical connection between the grounding pin and the wafer.
