Abstract: A method and a system for analyzing a measurement-yield correlation are provided. The method for analyzing a measurement-yield correlation according to an embodiment of the present invention derives a first yield prediction function by using measurement-yield data which are data pairs of process result data measured after performing a process and actual yield data for each of the collected process result data, extracts some of the measurement-yield data by using a first yield prediction function, and subsequently derives a second yield prediction function by using the extracted measurement-yield data. As such, the measurement-yield correlation indicating high correlation/reliability can be derived, so that a final yield can be predicted relatively accurately from the process result data measured after performing the process.
