Patent ID: 7593564

Claim:
A defect reviewing apparatus comprising: an input unit for inputting inspection information of a defect to be inspected, said inspection information being obtained by an inspection apparatus; a display unit for displaying a magnified image of said defect to be inspected, based on position coordinates of said defect, said position coordinates being input through said input unit; and a defect data analyzing/computing portion for analyzing errors included in said position coordinates of said defect, wherein: said defect data analyzing/computing portion determines a deviation of inspection coordinates with respect to absolute coordinates as an error caused by said inspection apparatus, estimates a random error based on said error, and sets a view size for defect search in said display unit based on said random error, when said absolute coordinates designate position coordinates of a defect in a known calibrating substrate, and said inspection coordinates designate position coordinates of said defect of said calibrating substrate detected by said inspection apparatus, said input unit inputs a detected value of a defect size of said calibrating substrate detected by said inspection apparatus, and said defect data analyzing/computing portion determines a correlation between said detected value of said defect size and a real value of said defect size measured in advance, and selects a defect in which said correlation is higher than a predetermined threshold value, as a defect suitable for fine alignment.
