Abstract
Reticles are selected for use in a wafer processing system based on the wafer-processing recipe and on the level of degradation exhibited by the reticle after multiple exposures to light and constant physical handling. In an example embodiment of an integrated reticle sorter and stocker, a scanner identifies the reticle and gathers dimensional data on each reticle. A sorter sorts reticles within reticle pods according to the processing recipe and stores the pods within a storage location in the stocker. A computer arrangement then records information from the scanner and the sorter and assesses whether any of the reticles has degraded beyond an acceptable level of usage.
