Abstract
A substrate processing system includes: an acquiring unit that acquires a plurality of types of time-series data for each time when a plasma processing is performed on a substrate; a learning unit that generates a number of learned abnormal value detection models corresponding to a number of the plurality of types of the time-series data by calculating a data density of each of the plurality of types of time-series data acquired in a first phase; and a quantification unit that quantifies a state in a processing space in a second phase by inputting the plurality of types of time-series data acquired in the second phase into the corresponding learned abnormal value detection models, respectively, and calculating a divergence degree from the plurality of types of the time-series data acquired in the first phase.
