    摘要: PROBLEM TO BE SOLVED: To detect a minute defect, measure dimensions of the detected defect with high accuracy, non-destructively inspect a sample and obtain substantially fixed inspection results related to a number, a position, the dimensions and a defect type of the detected defect to inspect a large number of samples within a given amount of time.SOLUTION: A defect inspection apparatus comprises: irradiating means for irradiating a linear region on a sample surface with illumination light; detecting means for detecting reflected and scattered light from the linear region on a sample irradiated with the light by the irradiating means; and signal processing means for processing a signal obtained by detecting the reflected and scattered light to detect the defect on the sample. The detecting means is equipped with: an optical system for dispersing the reflected and scattered light from the sample in one direction and for image forming in a direction orthogonal to the one direction; and a detection system for detecting the reflected and scattered light dispersed in the one direction and image formed in the direction orthogonal to the one direction by the optical system, by using an array sensor in which detection pixels are two-dimensionally arranged, and for adding an output signal of every detection pixel arranged in a line in the direction in which the reflected and scattered light is dispersed and outputting the summed output signal.
