    摘要: A method and apparatus of detecting a defect by inspecting a specimen in which a surface of a specimen on which plural patterns are formed is illuminated with an elongated shape light flux from one of plural directions which are different in elevation angle by switching an optical path of the light flux emitted from an illuminating light source in accordance with a kind of defect to be detected. Plural optical images of the specimen illuminated by the elongated shape light flux are captured with plural image sensors installed in different elevation angle directions by changing an enlarging magnification in accordance with a density of the pattern formed on the sample in an area irradiated with the illuminating elongated shape light flux. A defect on the specimen is detected by processing the images captured by the plural image sensors.

    摘要: An inspection apparatus projects a laser beam on the surface of a SOI wafer and detects foreign matter on and defects in the surface of the SOI wafer by receiving scattered light reflected from the surface of the SOI wafer. The wavelength of the laser beam used by the inspection apparatus is determined so that a penetration depth of the laser beam in a Si thin film may be 10 nm or below to detect only foreign matter on and defects in the outermost surface and not to detect foreign matter and defects in a BOX layer. Only the foreign matter on and defects in the outermost surface layer can be detected without being influenced by thin-film interference by projecting the laser beam on the surface of the SOI wafer and receiving scattered light rays.
