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 6):
The defect inspection method according to  claim 3 , wherein the inspection object is a laminated semiconductor wafer formed by laminating a plurality of wafers having multiple types of patterns formed thereon, and wherein an internal defect is detected in an internal sectional image of the laminated semiconductor wafer parallel to the surface by applying the same labels to regions having the same combination of the patterns formed on the laminated plurality of wafers, constituting a partial sectional image group comprising the regions applied with the same labels, and integrating the features of the partial sectional image in the partial sectional image group belonging to the respective labels.
