Patent ID: 7058470

Claim:
A semiconductor processing apparatus for processing a semiconductor wafer, comprising: a sensor for monitoring a processing state of said semiconductor processing apparatus; a processing result input unit which inputs measured values for processing results of a semiconductor wafer processed by said semiconductor processing apparatus; a model equation generation unit relying on sensed data acquired by said sensor and said measured values to generate a model equation for predicting a processing result using said sensed data as an explanatory variable; a processing result prediction unit which predicts a processing result based on said model equation and said sensed data; and a process recipe control unit which compares said predicted processing result with a previously set value to control a processing condition of said semiconductor processing apparatus such that a deviation between said predicted processing result and said previously set value is corrected, wherein said process recipe control unit includes a controller which controls at least one of a plurality of different processing performances for the processing of the semiconductor wafer without effecting change of others of the plurality of different processing performances.
