Abstract:
A system for analyzing defects comprises determining coordinates of a defect using a wafer inspection tool; identifying a structure of interest near the defect coordinates; directing a focused ion beam toward the wafer to expose the structure of interest; and forming an image of the exposed structure of interest, wherein the focused ion beam is directed to the mill at a location corresponding to the identified structure of interest rather than at the coordinates of the defect.
