Patent ID: 7596423

Claim:
A method of verifying a Site-Dependent (S-D) processing procedure, the method comprising: receiving a plurality of wafers by a S-D transfer system, each wafer having one or more layers thereon and having wafer data associated therewith, wherein the S-D transfer system is coupled to one or more subsystems in a processing system, the wafer data including historical and/or real-time data; determining S-D wafer state data for each wafer; establishing a first set of verification wafers using the S-D wafer state data and the wafer data, wherein the first set of verification wafers comprise a number of S-D wafers; determining a number of required verification sites for each verification wafer using the S-D wafer state data; determining a number of visited verification sites for each verification wafer using the S-D wafer state data; determining a number of remaining verification sites for each verification wafer using a difference between the number of required verification sites and the number of visited verification sites; establishing a first procedure-verification sequence for a first verification wafer in the first set of verification wafers using the wafer data, the process state data, the number of required verification sites, the number of verification visited sites, or the number of remaining verification sites or any combination thereof; determining a first S-D verification procedure for the first verification wafer, wherein the first S-D verification procedure is determined using the procedure-verification sequence and comprises one or more processing procedures; transferring the first verification wafer to a first S-D processing element in a first processing subsystem using a S-D transfer subsystem coupled to the first processing subsystem when the first S-D processing element is available; and delaying the first verification wafer for a first period of time using the S-D transfer subsystem coupled to the first processing subsystem when the first S-D processing element is not available.
