Abstract: Methods are disclosed for forming fins in transistors. In one embodiment, a method of fabricating a device includes forming silicon fins on a substrate and forming a dielectric layer on the substrate and adjacent to the silicon fins such that an upper region of each silicon fin is exposed. Germanium may then be epitaxially grown germanium on the upper regions of the silicon fins to form germanium fins.

Abstract: Methods of forming microelectronic structures are described. Embodiments of those methods include forming a nanowire device comprising a substrate comprising source/drain structures adjacent to spacers, and nanowire channel structures disposed between the spacers, wherein the nanowire channel structures are vertically stacked above each other.

Abstract: Nanowire structures having non-discrete source and drain regions are described. For example, a semiconductor device includes a plurality of vertically stacked nanowires disposed above a substrate. Each of the nanowires includes a discrete channel region disposed in the nanowire. A gate electrode stack surrounds the plurality of vertically stacked nanowires. A pair of non-discrete source and drain regions is disposed on either side of, and adjoining, the discrete channel regions of the plurality of vertically stacked nanowires.

Abstract: Embodiments of the present disclosure relate to non-planar semiconductor device structures having fins. In one embodiment, a semiconductor device includes a substrate, silicon fins positioned on the substrate, and a germanium layer that is epitaxially grown on an upper region of the silicon fins with the silicon fins and the germanium layer forming a body of the semiconductor device.

Abstract: Semiconductor devices having metallic source and drain regions are described. For example, a semiconductor device includes a gate electrode stack disposed above a semiconducting channel region of a substrate. Metallic source and drain regions are disposed above the substrate, on either side of the semiconducting channel region. Each of the metallic source and drain regions has a profile. A first semiconducting out-diffusion region is disposed in the substrate, between the semiconducting channel region and the metallic source region, and conformal with the profile of the metallic source region. A second semiconducting out-diffusion region is disposed in the substrate, between the semiconducting channel region and the metallic drain region, and conformal with the profile of the metallic drain region.
