Patent ID: 7601954

Claim:
A method for reviewing defects of a sample including these steps: a first step for, on the basis of position information of defects on a sample placed on a table that can move in an X-Y plane, where the position information of defects is previously detected and obtained by inspecting the sample by an other inspection system, driving the table and making the defects come into the viewing field of an optical microscope, and adjusting a focus of a detection optical system of the optical microscope onto the sample; a second step for re-detecting the defects by the optical microscope; a third step for correcting the position information of defects on the basis of the position information of defects re-detected at the second step; and a fourth step for reviewing the defects whose position information is corrected at the third step by an electron microscope, wherein at the first step, adjusting the focus of the detection optical system of the optical microscope onto the sample is made by moving a part of or a whole of the detection optical system in a normal line direction of the sample surface.
