Method and system for calibrating measurement tools for semiconductor device manufacturing
摘要:
A method and system for calibrating a plurality of measurement systems. The method includes obtaining a first plurality of calibration standards. The first plurality of calibration standards is associated with a plurality of predetermined values. Additionally, the method includes measuring the first plurality of calibration standards by a plurality of measurement systems to obtain a first plurality of measured values, processing information associated with the first plurality of measured values, and selecting a first measurement system from the plurality of measurement systems based on at least information associated with the first plurality of measured values. Moreover, the method includes calibrating the first measurement system with the first plurality of calibration standards, obtaining a second plurality of calibration standards, and measuring the second plurality of calibration standards by the first measurement system to obtain a second plurality of measured values.
