Abstract
A method and system for processing commonality of semiconductor devices. The method includes providing a first plurality of semiconductor devices, providing a second plurality of semiconductor devices, obtaining a first plurality of measured values corresponding to a characteristic associated with the first plurality of semiconductor devices, and obtaining a second plurality of measured values corresponding to the characteristic associated with the second plurality of semiconductor devices. Additionally, the method includes performing a first statistical analysis, determining a first statistical distribution, performing a second statistical analysis, and determining a second statistical distribution. Moreover, the method includes processing information associated with the first statistical distribution and the second statistical distribution, and determining an indicator. Also, the method includes processing information associated with the indicator, determining a confidence level, processing information associated with the confidence level, and determining whether the characteristic is stable.
