Three terminal fuse structure created by oxygen vacancy traps in hafnium-based oxides

摘要

A fuse structure includes a substrate, a gate dielectric formed on the substrate, a gate electrode formed on the gate dielectric, and first and second source/drain regions formed on the substrate on opposite sides with respect to the gate electrode, wherein the gate dielectric is configured such that a plurality of oxygen vacancies trapping respective charges are formed upon application of a pulse to the gate electrode.
