IMAGE INSPECTION METHOD OF DIE TO DATABASE |
摘要 |
An image inspection method of die to database is provided, and the positions in the to-be-inspected chips within one wafer may be selected. In the method, a plurality of inspection areas in a plurality of positions in the to-be-inspected chips within a wafer are selected, a plurality of raw images of the inspection areas are obtained, and a plurality of locations of the raw images are then decoded. After that, an image extraction is performed on the raw images to obtain a plurality of image contours. Thereafter, the image contours are compared with a design database of the chip in order to obtain a result of a defect inspection, and execute the same thing in whole wafer. |
