Manufacturing Quality Improvement Through Statistical Root Cause Analysis Using Convolution Neural Networks

A quality improvement method for an image sensor array includes collecting in-line optical inspection data of the image sensor, collecting end of line electrical data of the image sensor, creating defect maps and obtaining x-y coordinates of the optical inspection data and the electrical data, correlating the defect maps to generate correlated defects, classifying the images of the correlated defects, and generating root cause statistics of the classified correlated defects.
