The present invention includes a method of verifying a Site-Dependent
(S-D) processing procedure, the method including receiving a plurality of
wafers by a S-D transfer system, determining S-D wafer state data for
each wafer; establishing a first set of verification wafers, determining
a number of required verification sites for each verification wafer,
determining a number of visited verification sites, determining a number
of remaining verification sites for each verification wafer, establishing
a first procedure-verification sequence, determining a first S-D
verification procedure, transferring the first verification wafer to a
first S-D processing element and delaying the first verification wafer
for a first period of time.
