| Abstract(in English) | Reductions of the noise caused by the pattern shape difference and the sampling errors are essential to recognize a minute defect on the complicated multilayer patterns on wafers. We propose a highly sensitive comparison inspection method with noise reducion. We generate a statistical pattern from plural repetitive patterns and we compare the detected image with the statistical pattern. The grayscale is converted so that the grayscales of the two images are matched and the difference is compressed using Maharanobis distance according to the grayscale fluctuation. This new method can detect small defects without the influence of pattern roughness. |
