Claim One:
1. A method of determining a condition of a process in a substrate processing module, comprising: obtaining a first set of time-series data from measurement of a process parameter during a first occurrence of a process; obtaining at least a second set of time-series data from measurement of the process parameter during at least a second occurrence of the process; identifying a structure corresponding to a first portion of the first set of time-series data, the structure selected from a finite set of structures; identifying a first portion in each of the at least a second set of time series data that correspond to the structure; deriving a composite model from the first portion of the first set of time-series data and the first portion of each of the at least a second set of time series data; obtaining a third set of time-series data from measurement of the process parameter during a third occurrence of the process; and determining a degree of correlation between a portion of the third set of time-series data and the composite model.
