Patent ID: 11922613
Assignee: MICRON TECHNOLOGY, INC.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 4:
5. A system, comprising:
an image capturing device configured to capture an image of a wafer;
an inspection system comprising a classification system configured to use 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;
a validation system configured to validate the classification for the captured image by determining whether a dominant probability value in the classification is above a threshold, wherein the classification comprises a probability for each of the plurality of classes to which the captured image belongs; and
a training system configured to, upon failure of validating the classification, retrain the classification CNN by updating weights of the classification CNN based at least partially on the captured image.
