Zusammenfassung:Methods of modeling across reticle variations and a related reticle are disclosed. One embodiment of the method includes defining a test for determination across a multiple chip wafer; identifying a measurement structure for performing the test; implementing the measurement structure on the multiple chip wafer using a reticle including the measurement structure between copies of the multiple chips on the reticle, wherein no one of the multiple chips covers an entirety of the reticle; performing the test on the multiple chip wafer using the measurement structure to acquire data across the reticle; using data from the performing to establish an across reticle variation model; and using the across reticle variation model to predict across chip variation for at least one of the multiple chips.
