Abstract
Systems for reliability testing include a picometer configured to measure a leakage current across a device under test (DUT); a camera configured to measure optical emissions from the DUT based on a timing of the measurement of the leakage current; and a test system configured to apply a stress voltage to the DUT and to correlate the leakage current with the optical emissions using a processor to determine a time and location of a defect occurrence within the DUT by locating instances of increased noise in the leakage current that correspond in time with instances of increased optical emissions.
