Chip sorting anti-dislocation method and device, terminal and storage medium

The invention relates to the technical field of semiconductor device manufacturing, in particular to a chip sorting dislocation prevention method and device, a terminal and a storage medium, and the method comprises the steps: obtaining a wafer image, carrying out the preprocessing of the wafer image, obtaining the coordinates of a taken chip and the coordinates of a non-taken chip through the preprocessed wafer image, and obtaining the coordinates of the taken chip and the coordinates of the non-taken chip; the coordinate is compared with the MAP to determine whether the taken-down chip is consistent with the indication of the MAP, so that the problem of mistaken taking caused by accumulated error of the chip position of the wafer taken out by the equipment when the row and column spacing of the wafer is inconsistent in the sorting stretching frame can be avoided. According to the method, the chip taking accuracy is high, when the method is operated on a computing terminal, the processing speed can be greatly increased, the manual confirmation and tracking process is reduced, and the labor efficiency is improved.
