By applying a bias on the defective circuit and irradiating the region of interest with e-beam, the electron interaction induced localized heating changes the defect resistance. The current sensed varies while the defect is irradiated...

Further, altering the resistance of the structure investigated is only adequate in the context of localization, not when mapping of intrinsic resistance is required. Further, EBIRCh requires that a constant...
