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 14):
The ultrasonic inspection apparatus according to  claim 13 , wherein the image processing unit further comprises a partial sectional image group generation unit grouping the sectional images generated by the sectional image generation unit into partial sectional image groups each consisting of regions constituted by the same pattern, and the reference image generation unit generates the reference image that does not include a defect from each partial sectional image and generates the multi-value mask for masking a non-defective pixel from the obtained internal sectional image of the inspection object, in each partial sectional image group grouped by the partial sectional image group generation unit.
