Abstract
A method for detecting word line shorts in a memory device includes: determining a region of interest (ROI) region in a bright voltage contrast (BVC) image for contact through-holes (CTs) of word lines in the memory device, the CTs comprising first CTs in at least one first word line that is electronically charged and second CTs in at least one second word line that is not electronically charged, and the ROI region comprising the at least one first word line; determining coordinates of each CT in the ROI region; reviewing a grayscale value at a position of the coordinates of each CT in the ROI region to determine whether the CT is a defective CT; and displaying the defective CT in response to the defective CT being determined.
