Patent ID: 6870169

Claim:
A method of analyzing the compositions of defects, the method comprising the steps of: moving a stage and setting a sample placed on the stage to an observation position; obtaining a secondary particle image of a first resolution of the sample by irradiating and scanning a first electron beam focused on the sample set at the observation position and detecting secondary particles emitted from the sample; determining the position of a defect on the sample using the secondary particle image of the first resolution of the sample; obtaining a secondary particle image of a second resolution of the sample by irradiating and scanning an electron beam focused on the determined position of the defect and detecting secondary particles emitted from the sample; obtaining information of a defect region on the sample using the secondary particle image of the second resolution of the sample; selecting a target defect to be analyzed on the basis of the obtained information of the defect region; and obtaining information of the composition of the target defect by irradiating a second electron beam focused on the selected target defect and analyzing the selected target defect.
