    摘要: An aspect of the invention provides a defect inspection apparatus being able to accurately inspect a micro foreign matter or defect at a high speed for an inspection target substrate in which a repetitive pattern and a non-repetitive pattern are mixed. In a foreign matter anti-adhesive means 180, a transparent plate 187 is placed on a placement table 34 through a frame 185. In the foreign matter anti-adhesive means 180, a shaft 181 which is rotatably supported by two columnar supports 184 fixed onto a base 186 is coupled to a motor 182 by a coupling 183. The shaft 181 is inserted into a part of a frame 185 between the two columnar supports 184 such that the frame 185 and the transparent plate 187 are turnable about the shaft 181. Therefore, the whole of the frame 185 is opened and closed in a Z-direction about the shaft 181, and a wafer 1 on the placement table 34 can be covered with the frame 185 and the transparent plate 187.

    摘要: A pattern defect inspection apparatus capable of detecting minute defects on a sample with high sensitivity without generating speckle noise in signals is realized. Substantially the same region on a surface of a wafer is detected by using two detectors at mutually different timings. Output signals from the two detectors are summed and averaged to eliminate noise. Since a large number of rays of illumination light are not simultaneously irradiated to the same region on the wafer, a pattern defect inspection apparatus capable of suppressing noise resulting from interference of a large number of rays, eliminating noise owing to other causes and detecting with high sensitivity minute defects on the sample without the occurrence of speckle noise in the signal can be accomplished.
