Patent ID: 8232620

Claim:
A structure, comprising: a substrate; a first electrode in the substrate, wherein a first direction is oriented perpendicular to a top surface of the first electrode, and wherein the first electrode comprises a first electrically conductive material; a first dielectric layer above both the substrate and the first electrode in the first direction, wherein a top surface of the first dielectric layer is further from the top surface of the first electrode than is any other surface of the dielectric layer, and wherein the first dielectric layer comprises a first dielectric material and a second dielectric material; a second dielectric layer above the first dielectric layer in the first direction, wherein a bottom surface of the second dielectric layer is in direct physical contact with the top surface of the first dielectric layer, and wherein the second dielectric layer comprises the second dielectric material; a fuse element buried in the first dielectric layer, wherein a bottom surface of the fuse element is in direct physical contact with the top surface of the first electrode, and wherein a top surface of the fuse element is coplanar with the top surface of the first dielectric layer and is in direct physical contact with the bottom surface of the second dielectric layer; and a second electrode in the second dielectric layer and above the fuse element in the first direction, wherein the first electrode and the second electrode are electrically coupled to each other through the fuse element, wherein the second electrode comprises a second electrically conductive material, and wherein the first direction is oriented perpendicular to the top surface of the first dielectric layer, the bottom surface of the second dielectric layer, the bottom surface of the fuse element, and the top surface of the fuse element.
