Abstract:
Methods of fabricating a capped interconnect for a microelectronic device which includes a sealing feature for any gaps between a capping layer and an interconnect and structures formed therefrom. The sealing features improve encapsulation of the interconnect, which substantially reduces or prevents electromigration and/or diffusion of conductive material from the capped interconnect.
