Abstract: An electrical fuse device is disclosed. A circuit apparatus can include the fuse device, a first circuit element and a second circuit element. The fuse includes a first contact that has a first electromigration resistance, a second contact that has a second electromigration resistance and a metal line, which is coupled to the first contact and to the second contact, that has a third electromigration resistance that is lower than the second electromigration resistance. The first circuit element is coupled to the first contact and the second circuit element coupled to the second contact. The fuse is configured to conduct a programming current from the first contact to the second contact through the metal line. Further, the programming current causes the metal line to electromigrate away from the second contact to electrically isolate the second circuit element from the first circuit element.

The structure includes a metallization feature comprising a fill material and formed within a dielectric layer; at least one cap covering the fill material of the metallization feature, the at least one cap is comprised of a material different than the fill material of the metallization feature; and an interconnect structure in electrical contact with the metallization feature.

Abstract: A method of forming a titanium nitride (TiN) diffusion barrier includes exposing a deposition surface to a first pulse of a titanium-containing precursor and to a first pulse of a nitrogen-rich plasma to form a first TiN layer with a first nitrogen concentration making a lower portion of the TiN diffusion barrier, the first nitrogen concentration of the first TiN layer is increased by the first pulse of the nitrogen-rich plasma reducing a reactivity of the lower portion of the TiN diffusion barrier to prevent fluorine diffusion. The first TiN layer is exposed to second pulses of the titanium-containing precursor and the nitrogen-rich plasma to form a second TiN layer with a second nitrogen concentration above the first TiN layer making an upper portion of the TiN diffusion barrier, the first pulse of the nitrogen-rich plasma has a substantially longer duration than the second pulse of the nitrogen-rich plasma.

Abstract: Structures for a field-effect transistor and methods for forming a structure for a field-effect transistor. A gate cavity is formed in a dielectric layer that includes a bottom surface and a plurality sidewalls that extend to the bottom surface. A gate dielectric layer is formed at the sidewalls and the bottom surface of the gate cavity.
