Abstract
A device includes image generation circuitry and convolutional-neural-network circuitry. The image generation circuitry, in operation, generates a digital image representation of a wafer defect map (WDM). The convolutional-neural-network circuitry, in operation, generates a defect classification associated with the WDM based on the digital image representation of the WDM and a data-driven model generated using an artificial wafer defect digital image (AWDI) data set and associating AWDIs with classes of a defined set of classes of wafer defects. A wafer manufacturing process may be controlled based on the classifications of WDMs.
