Abstract:
1. A system for controlling a semiconductor processing apparatus having an input recipe stored therein, the control system comprising: a control server connected to the semiconductor processing apparatus through a first communication interface; an operator interface connected to the control server through a second communication interface; a verification server separate from the control server connected to the control server through a third communication interface, the verification server comprising a range specification verification unit; and, a database connected to the verification server through a fourth communication interface, the database storing recipes available for the semiconductor processing apparatus and verification data comprising a range specification for input parameter values included in the input recipe; wherein the range specification verification unit determines whether or not the input parameter values associated with the input recipe are within allowable ranges according to the range specification, and the verification server communicates to the operator interface, in accordance with the determination of the range specification verification unit, information controlling whether or not a fabrication process indicated by the input recipe will be performed.
