Abstract:
1. A method of controlling a semiconductor manufacturing apparatus comprising: obtaining a plurality of processing parameters for processing a wafer, wherein the processing parameters comprise processing conditions of the semiconductor manufacturing apparatus; obtaining a target parameter that is measured from the wafer processed with the plurality of processing parameters; calculating a model formula, comprising: obtaining the selected parameter of a processing while the processing is being performed by the semiconductor manufacturing apparatus; calculating a predicted value of the target parameter of the wafer being processed by use of the model formula and the selected parameter, while the processing is being performed; calculating a value to be modified of a modification parameter, the modification parameter being one or more of the plurality of processing parameters of the processing being performed by the semiconductor manufacturing apparatus on the basis of the predicted value, while the processing is being performed; and performing the processing continuously by use of the value to be modified of the modification parameter.
