Zusammenfassung: | An apparatus diagnostic apparatus that performs a computation process using data acquired from a semiconductor apparatus manufacturing apparatus having a reference chamber to create reference chamber feature quantity map data by mapping a feature quantity onto a graph having axes representing a plurality of parameters. The apparatus diagnostic apparatus also performs a computation process using data acquired from a semiconductor apparatus manufacturing apparatus having a calibration-target chamber to create calibration-target chamber feature quantity map data by mapping a feature quantity onto a graph having axes representing a plurality of parameters. Based on patterns observed in the reference chamber feature quantity map data and the calibration-target chamber feature quantity map data, the apparatus diagnostic apparatus identifies a performance difference between different chambers, a performance difference resulting from a temporal change of a single chamber, or a performance difference resulting from co |
