Abstract:
1. A prediction apparatus for a plasma processing apparatus, which predicts a condition of the plasma processing apparatus or state of an object to be processed based on an operation data of the plasma processing apparatus and a processing result data acquiring the condition of the plasma processing apparatus or state of the object to be processed as processing result in a process of carrying out plasma processing with respect to the object to be processed in a process chamber of the plasma processing apparatus, comprising: data collecting means for collecting an operating data and the processing result data; operation data selecting means for making multivariate analysis with respect to the collected operation data, and selecting the operation data used for prediction based on the analysis result; analysis means for finding a correlation between the selected operation data and the processing result data; and prediction means for predicting a condition of the plasma processing apparatus or state of the object to be processed using an operation data when objects to be processed other than the object to be processed used for obtaining the correlation are processed, based on the correlation found by the analysis means.
