Abstract: Embodiments of the disclosure are in the field of integrated circuit structure fabrication. In an example, an integrated circuit structure includes a plurality of conductive lines, individual ones of the plurality of conductive lines having a liner including molybdenum (Mo), and a fill including tungsten (W). The integrated circuit structure also includes an inter-layer dielectric (ILD) structure having portions between adjacent ones of the plurality of conductive lines.

Abstract: Transistor structures comprising a gate electrode, or “gate,” that is self-aligned to underlying channel material. A mask material employed for patterning the channel material is further employed to define a cap of mask material having a larger width that protects a portion of gate material during a gate etch. The cap is therefore self-aligned to the channel material so that an amount by which a gate material extends laterally beyond the channel material is ensured to be symmetrical about a centerline of the channel material.
