Abstract

The present invention relates to a method for inspecting a skeleton wafer (1), comprising the steps of (i) performing template matching of at least one skeleton wafer image and at least one processed wafer image (101); (ii) rescaling said skeleton wafer image to match the processed wafer image's size (103); and (iii) computing differences between said skeleton wafer image and said processed wafer image (107); Gaussian mask convolution is performed on at least one electronic component of said skeleton wafer image to suppress weight on at least one edge of said skeleton wafer image (105), said step is done after step (ii) and prior to step (iii).
