Abstract
Electrical fuses and methods for forming an electrical fuse. The electrical fuse includes a current shunt formed by patterning a first layer comprised of a first conductive material and disposed on a top surface of a dielectric layer. A layer stack is formed on the current shunt and the top surface of the dielectric layer surrounding the current shunt. The layer stack includes a second layer comprised of a second conductive material and a third layer comprised of a third conductive material. The layer stack may be patterned to define a fuse link as a first portion of the layer stack directly contacting the top surface of the dielectric layer and a terminal as a second portion separated from the top surface of the dielectric layer by the current shunt.
