Patent ID: 6881352

Claim:
A plasma processing control method for controlling a plasma processing apparatus performing plasma processing to a sample accommodated Within a vacuum processing chamber of the processing apparatus, comprising the steps of: monitoring process parameters during the processing operation for the sample; estimating a processed result on the basis of a result of said monitoring step; calculating correction values of processing conditions and generating an optimum recipe on the basis of an estimated result of said estimating step such that the processed result becomes a target value; previously dividing processing conditions of a plurality of items into two of processing conditions which influence uniformity of a processed result in a sample surface and processing conditions which do not influence the uniformity; and optimizing the processing conditions which influence the uniformity from the viewpoint of uniformity; wherein said step of generating an optimum recipe includes a step of calculating and correcting correction values of only the processing conditions which do not influence the uniformity in such a manner that the processed result coincides with the target value, combining with the previously-optimized processing conditions which influence the uniformity, and generating an optimum recipe; and controlling the plasma processing apparatus on the basis of said generated optimum recipe.
