    摘要: A defect-inspecting apparatus including an arrangement to convert detected light into a first signal corresponding to light illuminated by a high-angle illumination optical system and/or a second signal corresponding to light illuminated by a low-angle illumination optical system; and a classification unit which utilizes the first and second signal and classifies defects on the object to be inspected, wherein a defect size is estimated by changing a correction coefficient of the defect size on a basis of a concave-convex level (b/a), where the concavo-convex level (b/a) of a defect is indicated by a ratio of a size b of a first direction of the defect to a size a of a second direction of the defect, where the second direction is lateral to the first direction.

    摘要: The present invention is characterized by the following: incident illumination and oblique illumination are performed on a scratch and a foreign material, which have been made on a surface of a polished or a ground insulating layer, with substantially the same luminous flux; and on the basis of a correlation such as a ratio of intensity of scattered light generated by the shallow scratch and the foreign material between the incident illumination and the oblique illumination, the shallow scratch is discriminated from the foreign material.

    摘要: Conventionally, a particle/defect inspection apparatus outputs a total number of detected particles/defects as the result of detection. For taking countermeasures to failures in manufacturing processes, the particles/defects detected by the inspection apparatus are analyzed. Since the inspection apparatus outputs a large number of detected particles/defects, an immense time is required for analyzing the detected particles/defects, resulting in a delay in taking countermeasures to a failure in the manufacturing processes. In the present invention, an apparatus for optically inspecting particles or defects relates a particle or defect size to a cause of failure in an inspection result. A data processing circuit points out a cause of failure from the statistics on the inspection result, and displays information on the inspection result. A failure analysis is conducted by setting a threshold for identifying a failure in each of regions on a semiconductor device or the like to statistically evaluate detected particles.
