Abstract:
Provided are methods of testing pattern reliability and methods of testing a semiconductor device using the same. A method of testing pattern reliability may include acquiring an optical image of a wafer on which a plurality of patterns are formed, evaluating degrees of damage of ones of the plurality of patterns based on the optical image, determining a respective reliability of the ones of the plurality of patterns according to the evaluated respective degrees of damage, and mapping the reliability of the ones of the plurality of patterns based on locations of the respective patterns on the wafer.
