Claim 4:
5. The method of claim 1, wherein the wafer detection model is acquired by training through a training sample based on a deep neural network model, an acquiring procedure of the training sample comprising:
acquiring a wafer picture sample and a marking result corresponding to the wafer picture sample, the marking result comprising a defect position where a wafer defect exists in the wafer picture sample;
performing the picture segmentation on the wafer picture sample to acquire a plurality of first segmented picture samples;
selecting a second segmented picture sample with the wafer defect from the plurality of first segmented picture samples according to the defect position in the wafer picture sample; and
taking the wafer picture sample and the second segmented picture sample as the training samples of the wafer detection model.
