Characteristic voltage of programmed metal-to-metal antifuses

The characteristic voltage V/sub f/ of different programmed metal-to-metal antifuses was measured and found to be nearly independent of the electrode materials. An electrothermal model, used previously to predict programmed silicon-electrode antifuse resistance, was extended to explain the above phenomenon. The metal-to-metal antifuse resistance vs. the programming current is governed by the Wiedeman-Franz Law.<
