Abstract:
1. A fuse for an integrated circuit, the fuse comprising: a first terminal portion and a second terminal portion interconnected by a fuse element, and wherein the first terminal portion and the second terminal portion reside over a first support and a second support, respectively, the first support and the second support being spaced apart, and wherein the fuse element bridges a distance between the first terminal portion over the first support and the second terminal portion over the second support, with the fuse, the first support and the second support defining a π-shaped structure in elevational cross-section through the fuse element; and wherein the first terminal portion, the second terminal portion and the fuse element are coplanar, and the fuse resides entirely over an isolation region in a semiconductor substrate, and wherein the first terminal portion and the second terminal portion are electrically contacted for programming of the fuse from above only.
