发明名称 ADOPTING FEATURE OF BURIED ELECTRICALLY CONDUCTIVE LAYER IN DIELECTRICS FOR ELECTRICAL ANTI-FUSE APPLICATION
摘要 An anti-fuse structure that included a buried electrically conductive, e.g., metallic layer as an anti-fuse material as well as a method of forming such an anti-fuse structure are provided. According to the present invention, the inventive anti-fuse structure comprises regions of leaky dielectric between interconnects. The resistance between these original interconnects starts decreasing when two adjacent interconnects are biased and causes a time-dependent dielectric breakdown, TDDB, phenomenon to occur. Decreasing of the resistance between adjacent interconnects can also be expedited via increasing the local temperature.
