Patent ID: 6892108

Claim:
A method for adjusting process parameters for at least one plate-shaped object in a processing tool, the plate-shaped object having experienced at least one preceding processing step performed by one processing device out of at least one set of processing devices, an adjustment in the processing tool being controlled by a control unit, which comprises the steps of: providing the plate-shaped object to the processing device; processing the plate-shaped object; generating a tag associated with the plate-shape object and representing a processing parameter offset of the processing device used in the processing step; transferring the tag to the control unit; transferring the plate-shaped object to a metrology tool; performing at least one measurement selected from the group consisting of a critical dimension measurement and an overlay measurement; forwarding metrology results of the measurement to the control unit; transferring the plate-shaped object to the processing tool; calculating a new set of values of the process parameters in response to the metrology results and the tag; adjusting the processing tool using the new set of values of the process parameters resulting in adjusted process parameters; and performing a process step on the plate-shaped object in the processing tool using the adjusted process parameters.
