- A second application of the software package is off-line analysis. Data files generated by overlay metrology tools such as IVS or KLA can be opened with Overlay Booster. The software automatically calculates and displays process correction parameters for feeback to exposure tools. Vector map and lot or wafer statistics are displayed on a single screen. Other features include capability to save results of a group of data files, subtraction of two data files, and lens fingerprint analysis. These featuers can be used for stepper matching and monitoring.
