METHODS FOR IMPROVING OPTICAL INSPECTION AND METROLOGY IMAGE QUALITY USING CHIP DESIGN DATA

Abstract:

A system and method for enhancing image quality. The system and method acquire a machine learning model trained for correlating one or more training images and one or more training design images. The system and method receive one or more sample specimen images corresponding to one or more features of a sample specimen. The system and method enhance the one or more sample specimen images by generating one or more enhanced images with the machine learning model based on at least the one or more sample specimen images.
