摘要: A method of monitoring a thermal processing system in real-time using a built-in self test (BIST) table that includes positioning a plurality of wafers in a processing chamber in the thermal processing system; executing a real-time dynamic model to generate a predicted dynamic process response for the processing chamber during the processing time; creating a first measured dynamic process response; determining a dynamic estimation error using a difference between the predicted dynamic process response and the measured dynamic process response; and comparing the dynamic estimation error to operational thresholds established by one or more rules in the BIST table.
