| 摘要 |
A metal-to-metal antifuse according to the present invention is disposed between a lower conductive electrode and an upper conductive electrode. The conductive electrodes may comprise either a barrier metal or a tungsten plug, and are each in electrical contact with a metal layer, usually a metal interconnect layer in an integrated circuit. An antifuse material is disposed between the lower and upper conductive electrodes and comprises a layer of amorphous silicon. The antifuse layer is sandwiched between two layers of silicon nitride.
