A method and system for multi-point (e.g., double-point) GOI test that can efficiently judge failure modes by testing only two points. We can measure leakage currents at only two voltages, which are the cut points of mode A-B and B-C, instead of the whole ramped voltages to save time and cost with the same test effectiveness according to a specific embodiment. By correlating leakage current at extrinsic field to the breakdown voltage, we can also evaluate the intrinsic reliability even if the samples are not subjected to actual breakdown according to a specific embodiment.
