摘要： A method for detecting an in-situ fast transient event within a processing chamber during substrate processing is provided. The method includes a set of sensors comparing a data set to a set of criteria (in-situ fast transient events) to determine if the first data set includes a potential in-situ fast transient event. If the first data set includes the potential in-situ fast transient event, the method also includes saving an electrical signature that occurs in a time period during which the potential in-situ fast transient event occurs. The method further includes comparing the electrical signature against a set of stored arc signatures. If a match is determined, the method yet also includes classifying the electrical signature as a first in-situ fast transient event and determining a severity level for the first in-situ fast transient event based on a predefined set of threshold ranges.
