Abstract: Embodiments of the invention include an interconnect structure and methods of forming such structures. In an embodiment, the interconnect structure may include an interlayer dielectric (ILD) with a first hardmask layer over a top surface of the ILD. Certain embodiments include one or more first interconnect lines in the ILD and a first dielectric cap positioned above each of the first interconnect lines. For example a surface of the first dielectric cap may contact a top surface of the first hardmask layer. Embodiments may also include one or more second interconnect lines in the ILD arranged in an alternating pattern with the first inter-connect lines. In an embodiment, a second dielectric cap is formed over a top surface of each of the second interconnect lines. For example, a surface of the second dielectric cap contacts a top surface of the first hardmask layer.

Abstract: Embodiments herein describe techniques for a semi-conductor device comprising a channel having a first semiconductor material; a source contact coupled to the channel, comprising a first Heusler alloy; and a drain contact coupled to the channel, comprising a second Heusler alloy. The first Heusler alloy is lattice-matched to the first semiconductor material within a first predetermined threshold. A first Schottky barrier between the channel and the source contact, and a second Schottky barrier between the channel and the drain contact are negative, or smaller than another predetermined threshold. The source contact and the drain contact can be applied to a strained silicon transistor, an III-V transistor, a tunnel field-effect transistor, a dichalcogenide (MX2) transistor, and a junctionless nanowire transistor.
