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.

摘要： A novel interlevel contact via structure having low contact resistance and improved reliability, and method of forming the contact via. The method comprises steps of: etching an opening through an interlevel dielectric layer to expose an underlying metal (Copper) layer surface; and, performing a low energy ion implant of an inert gas (Nitrogen) into the exposed metal underneath; and, depositing a refractory liner into the walls and bottom via structure which will have a lower contact resistance due to the presence of the proceeding inert gas implantation. Preferably, the inert Nitrogen gas reacts with the underlying exposed Copper metal to form a thin layer of CuN.
