Method and apparatus for run-to-run control of deposition process

摘要

A method and an apparatus for controlling a deposition process in a manufacturing process. A process recipe setting step is performed. A process run of semiconductor devices is performed based upon the process recipe. Metrology data relating to the process run of semiconductor dev determination is made whether production results are within a predetermined tolerance level, based upon the metrology data. Process recipe settings are modified in response to a determination that the production results are within a predetermined tolerance level, based upon the metrology data. A processing tool is capable of receiving at least one control input parameter and a metrology data acquisition unit is interfaced with the processing tool and is capable of acquiring metrology data from the processing tool. A production data analysis unit is interfaced with the metrology data acquisition unit and is capable of analyzing the metrology data from the metrology data acquisition unit and a control input parameter adjustment unit is interfaced with the production data analysis unit and the processing tool and is capable of performing adjustments upon the control input parameter.
