Use of Plasma Information in Machine-Learning-Based Fault Detection and Classification for Advanced Equipment Control

For advanced equipment control, two schemata of real-time fault detection were performed using machine learning algorithms in silicon etching in SF 6 /O 2 /Ar plasma. Fault detection and classification is investigated with the plasma state information with optical emission spectroscopy (OES) data to...
