| 摘要 |
In one illustrative embodiment, the method includes providing a wafer including at least one non-production area, forming a process layer above the wafer, forming a masking layer above the process layer, the masking layer being patterned so as to expose a portion of the process layer formed above the at least one non-production area, and performing a process operation on the exposed portion of the process layer formed above the at least one non-production area. In another aspect, the present invention is directed to a system that includes a controller for identifying at least one non-production area of a wafer, a photolithography tool for forming a masking layer above the process layer, the masking layer being patterned so as to expose a portion of the process layer formed above the at least one non-production area, and an etch tool for performing an etching process on the exposed portion of the process layer formed above the at least one non-production area.
