A method for characterizing identified defects during charged particle beam inspection of a sample is disclosed. The method comprises obtaining a voltage contrast image of the sample by using a charged particle beam imaging apparatus at an inspection temperature; identifying, from the voltage contrast image, the presence of at least one defect on the sample; providing reference data of the sample, wherein the reference data represents at least one reference defect on the sample; comparing the location or geographical distribution of the identified defects and the reference defects on the sample to correlate the identified defects with the inspection temperature thereby characterizing the identified defects.
