    摘要： A defects inspecting apparatus having: a scanning stage for running into a predetermined direction while mounting an inspection target substrate thereon; an illumination optic system for irradiating an illumination light beam upon a surface of the inspection target substrate at a predetermined angle inclined thereto; a detection optic system including, an upper-directed photo-detector for receiving upper-directed reflected/scattered lights emitting upwards from the inspection target substrate, thereby converting them into an upper-directed image signal, and a side-directed photo-detector for receiving side-directed reflected/scattered lights emitting for the inspection target substrate into an inclined direction, so as to flatly intersects the illumination light beam, and thereby converting into a side-directed image signal; and a signal processing system-for detecting defects upon basis of the upper-directed image signal and the side-directed image signal.
