Abstract:
1. A semiconductor processing system, comprising: a semiconductor processing apparatus for processing a semiconductor wafer; a plurality of sensors each 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 storage unit which stores a prediction model equation for predicting a processing result; a processing result prediction unit which predicts a processing result based on said prediction model equation stored in said model equation storage unit and sensed data acquired by said sensors; 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 a model equation generation unit relying on said sensed data and said measured values to generate said prediction model equation usinq said sensed data as an explanatory variable is provided at a remote location at least with respect to a location of said model equation storage unit, and said model equation generation unit transmits said generated prediction model equation to said model equation storage unit through a network to control the processing condition of said semiconductor processing apparatus by said process recipe control unit using said generated prediction model equation from said model equation storage unit.
