Abstract

The present invention relates to e-fuse devices, and more particularly to a device and method of forming an e-fuse device, the method comprising providing a first conductive layer connected to a second conductive layer, the first and second conductive layers separated by a barrier layer having a first diffusivity different than a second diffusivity of the first conductive layer. A void is created in the first conductive layer by driving an electrical current through the e-fuse device.
