Assignee: MICRON TECHNOLOGY, INC.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 5:
6. One or more computer-readable non-transitory storage media, the media encoded with instructions for performing operations comprising:
capturing an image of a wafer;
using a classification convolutional neural network (CNN) comprising multiple convolutional layers to determine a classification from a plurality of classes for the captured image, wherein each of the plurality of classes indicates a type of a defect in the wafer;
encoding a training image of a plurality of training images into a feature vector;
decoding the feature vector into a re-generated image;
clustering the feature vector into a cluster of a plurality of clusters;
determining a classification from the plurality of classes for the training image; and
training the classification CNN by repeating the encoding, the clustering, the decoding and the determining of classification in one or more iterations to determine weights of the classification CNN.
