Abstract: Methods and systems for detecting wafer shift/slide in a semiconductor process chamber have been disclosed. The vibration amplitude is measured in terms of acceleration because an increase in vibrational acceleration correlates with an increase of displacement of a wafer. The vibration of a chamber is measured. External vibratory forces acting on the chamber may be transmitted to the wafer inside the chamber.
