Abstract
A method for correlating semiconductor process data analyzes a semiconductor device that has been treated by a process, to produce process data related to the process. The data is converted into an image pattern, and automatic image retrieval is used to identify other devices having similar images. The process data is then correlated with prior process data of the other devices having the similar images.
