Abstract:
A method capable of accurately detecting a defect of a contact hole by using voltage contrast images is disclosed. This method includes: obtaining a plurality of voltage contrast images generated at different points in time; calculating average brightness levels of respective contact holes on each of the plurality of voltage contrast images; calculating a brightness index value which is an average of the average brightness levels of respective contact holes on each of the plurality of voltage contrast images; calculating a difference between an average brightness level of each contact hole on each voltage contrast image and the brightness index value that has been calculated for that voltage contrast image; calculating a sum of the differences that have been calculated for contact holes located at the same position in the plurality of voltage contrast images; comparing the sum of the differences with a defect threshold value; and detecting a defect of a contact hole with which the sum of the differences is larger than the defect threshold value.

Claim (Index 2):
The method according to  claim 1 , wherein said obtaining the plurality of voltage contrast images comprises obtaining a plurality of voltage contrast images generated at constant time intervals within a preset period of time.
