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： A method of inspecting defects of a sample on a movable table includes a first step for, on a basis of position information of the defects which is previously detected by an other inspection system, driving the table so that the defects come into a viewing field of an optical microscope having a focus which is adjusted, a second step for re-detecting the defects to obtain a first detection result, a third step for correcting the position information of defects on a basis of position information of the re-detected defects, and a fourth step for reviewing the defects whose position information is corrected to obtain a second detection result. At the second step, re-detecting is performed using reflection light or scattered light from the sample which passes an optical filter which includes a light shielding portion and a light transmitting portion.
