Abstract
A method and apparatus for detecting substrate arcing and breakage within a processing chamber is provided. A controller monitors chamber data, e.g., parameters such as RF signals, voltages, and other electrical parameters, during operation of the processing chamber, and analyzes the chamber data for abnormal spikes and trends. Using such data mining and analysis, the controller can detect broken substrates without relying on glass presence sensors on robots, but rather based on the chamber data.
