摘要： 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.

摘要： An extraneous substance inspection apparatus includes a level conversion circuit for converting a level of an extraneous substance detection signal obtained from a position in a first chip into one of multi-valued levels. A judging circuit determines the existence or absence of an extraneous substance by comparing a signal indicative of one of the multi-valued levels with another signal indicative of a converted level obtained by converting a detection signal detected at a similar position in another chip adjacent to the first chip.
