Abstract:
A method for automatic control of the operation of a processing tool arrangement of a kind utilizing photoresist-based processing, which is to be applied to a workpiece for providing certain process results, the method comprising:(i) applying a spectrophotometric measuring tool to the workpiece prior to processing said workpiece by a processing tool of said processing tool arrangement, measuring spectral characteristics of the workpiece indicative of at least one parameter of the workpiece that defines an optimal value of at least processing time parameter of said processing tool to be used in the processing of said workpiece to obtain certain process results, and generating measured data indicative of said spectral characteristics; (ii) analyzing said measured data and determining data indicative of the optimal value of said at least processing time parameter of said processing tool; (iii) utilizing said determined data to control the operation of the processing of said workpieces.
