An inspection method for contact by die to database is provided. In the method, a plurality of raw images of contacts in a wafer is obtained, and a plurality of locations of the raw images is then recoded to obtain a graphic file. After that, the graphic file is aligned on a design database of the chip. An image extraction is then performed on the raw images to obtain a plurality of image contours of the contacts. Thereafter, a difference in critical dimension between the image contours of the contacts and corresponding contacts in the design database are measured in order to obtain the inspection result for contacts in the wafer.

In the method, data of wafer mapping inspection are obtained first, and the data include images of defects in each of layers within a wafer and a plurality of physical coordinates of the defects.

The digital coordinates are converted into a plurality of physical locations, and the physical locations are overlapped with the physical coordinates so as to rapidly obtain correlations between the failure bits and the defects.
