Abstract: An apparatus and method for detecting defects on a specimen includes an illumination optical unit which obliquely projects a laser onto a region which is longer in one direction on a surface of a specimen than in a transverse direction, a table unit which mounts the specimen and which is movable, a detection optical unit which detects light from the specimen illuminated by the laser with an image sensor while the table is moving, and a signal processor. The signal processor processes a signal outputted from the image sensor of the detection optical unit and converted to a digital signal and extracts defects of the specimen by comparing the converted digital signal with a reference digital signal. A display unit displays information of defects extracted by the signal processor.

Abstract: A defect inspection method includes radiating an illumination slit-shaped beam having lights substantially parallel to a longitudinal direction to a substrate having circuit patterns in a direction inclined at a predetermined gradient relative to the direction of a line normal to the substrate and inclined at a predetermined gradient on a surface with respect to a group of main straight lines of the circuit patterns with its longitudinal direction oriented almost perpendicularly to a direction of a movement of the substrate. Scattered light reflected by a defect such as a foreign particle existing on the illuminated substrate is received and converted into a detection signal by using an image sensor, and defect judging is effected of an extracted a signal indicating a defect such as a foreign particle on the basis of the detection signal output.

Abstract: An apparatus for optically inspecting particles and/or defects correlates sizes of particles and/or defects to a cause of failure in an inspection result. A data processing circuit points out a cause of failure from the statistics on the inspection result, and displays information on the inspection result. A failure analysis is conducted by setting a threshold for identifying a failure in each of regions on a semiconductor device or the like to statistically evaluate detected particles.
