Zusammenfassung:According to an embodiment, a defect inspection method is performed with a defect inspection apparatus. The defect inspection apparatus is adapted to irradiate a first sample with illumination light to acquire a first sample image, and compare the first sample image to a reference image to inspect a defect. The defect inspection method includes generating the reference image, acquiring the first sample image, setting a defect detection condition using an index based on a result of defect inspection of a second sample different from the first sample, and discriminating a nuisance from a result of comparison between the reference image and the first sample image based on the defect detection condition.
