Method of making an antifuse structure using a metal cap layer
An antifuse includes a metal cap layer located at the second barrier layer of the antifuse to improve the antifuse yield and long term reliability. An antifuse further includes one or more interfacial oxide film layers surrounding an antifuse dielectric layer to provide narrowing of the antifuse pro...

| Zusammenfassung: | An antifuse includes a metal cap layer located at the second barrier layer of the antifuse to improve the antifuse yield and long term reliability. An antifuse further includes one or more interfacial oxide film layers surrounding an antifuse dielectric layer to provide narrowing of the antifuse programming voltage distribution and to further improve the antifuse yield and long term reliability. |
