Abstract:
1. A method comprising: forming a first metallization layer on an insulating layer, the first metallization layer including, in a substantially axial plane, a first portion of a first electrode of an anti-fuse structure; and a second electrode about the first portion of the first electrode, but separated therefrom; forming, in the substantially axial plane, a dielectric material surrounding the first portion of the first electrode, between the first portion of the first electrode and the second electrode; forming an interlayer dielectric (ILD) over the first metallization layer; forming at least one via through the ILD over the first portion of the first electrode; and forming a second metallization layer over the ILD, the second metallization layer including a second portion of the first electrode over the at least one via, wherein the at least one via electrically connects the first and second portions of the first electrode, wherein breakdown of a anti-fuse material is configured to enable an operating current to flow between the second electrode and the first electrode in a programmed state of the anti-fuse structure.
