Abstract:
In an ultrasonic inspection performed on an inspection object including a fine and multi-layer structure such as a semiconductor wafer and a MEMS wafer, a defect is detected by: separating a defect present inside from a normal pattern; obtaining an image of the inspection object by imaging the inspection object having a pattern formed thereon to enable a highly sensitive detection; generating a reference image that does not include a defect from the obtained image of the inspection object; generating a multi-value mask for masking a non-defective pixel from the obtained image of the inspection object; calculating a defect accuracy by matching the brightness of the image of the inspection object and the reference image; and comparing the calculated defect accuracy with the generated multi-value mask.

Claim (Index 11):
The defect inspection apparatus according to  claim 8 , wherein the detecting the defect is performed by integrating features of a plurality of images of the regions having the same pattern from among the multiple types of patterns formed thereon with respect to each pixel in the plurality of images and thereby calculating a reference value for each pixel, comparing the plurality of images with the calculated reference value, extracting a pixel exhibiting a largest deviation from the reference value as a candidate defect, and separating the extracted candidate defect into defective and non-defective using the multi-value mask.
