摘要： The present invention provides a defect inspecting apparatus and a defect inspection method for inspecting an object of inspection for a defect such as a foreign particle existing on the object wherein, by using a high-efficiency illumination optical system for radiating an illumination beam to the object of inspection from a direction to reduce the intensity of a scattered light generated by a pattern on the object of inspection, it is possible to decrease the intensity of the scattered light from the pattern which causes a variation of a signal and, in addition, by using a means for setting a detection threshold value based on a variation of a signal computed for each area in a chip on the object of inspection, the detection threshold value can be made small and, thus, the sensitivity as well as the throughput can be raised.
