Abstract
A current level extraction method for preventing cutoff is disclosed. The method may include starting a voltage sweep to an interconnection structure at a certain temperature, measuring an initial resistance of the interconnection structure, calculating a measured resistance of the interconnection structure according to a corresponding input voltage, determining whether or not a resistance ratio of the measured resistance of the interconnection structure to the initial resistance is equal to or less than a preset value, updating a current value corresponding to measured resistance to a potential maximum current level and repeating the step of calculating the measured resistance when the resistance ratio of the interconnection structure is equal to or less than the preset value, and setting the current value corresponding to the measured resistance as a maximum current level when the resistance ratio of the interconnection structure is greater than the preset value.
