Patent ID: 8610244

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 first 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, wherein the second dielectric layer comprises the second dielectric material different from the first dielectric material; and a fuse element buried in the first dielectric layer, wherein the second dielectric material differs from the first dielectric material, and wherein the fuse element is in direct physical contact with both the first dielectric material and the second dielectric material.
