A fin is formed over a first barrier layer over a substrate. The first barrier layer has a band gap greater than the band gap of the fin. In one embodiment, a gate dielectric layer is deposited on the top surface and opposing sidewalls of the fin and is adjacent to a second barrier layer deposited on the first barrier layer underneath the fin. In one embodiment, the gate dielectric layer is deposited on the top surface and the opposing sidewalls of the fin and an isolating layer is formed adjacent to the first barrier layer underneath the fin. In one embodiment, the gate dielectric layer is deposited on the top surface and the opposing sidewalls of the fin, and an isolating layer is formed adjacent to the second barrier layer deposited between the fin and the first barrier layer.

Deep gate-all-around semiconductor devices having germanium or group III-V active layers are described. For example, a non-planar semiconductor device includes a hetero-structure disposed above a substrate. The hetero-structure includes a hetero-junction between an upper layer and a lower layer of differing composition. An active layer is disposed above the hetero-structure and has a composition different from the upper and lower layers of the hetero-structure. A gate electrode stack is disposed on and completely surrounds a channel region of the active layer, and is disposed in a trench in the upper layer and at least partially in the lower layer of the hetero-structure. Source and drain regions are disposed in the active layer and in the upper layer, but not in the lower layer, on either side of the gate electrode stack.

Conductivity improvements in III-V semiconductor devices are described. A first improvement includes a barrier layer that is not coextensively planar with a channel layer. A second improvement includes an anneal of a metal/Si, Ge or SiliconGermanium/III-V stack to form a metal-Silicon, metal-Germanium or metal-SiliconGermanium layer over a Si and/or Germanium doped III-V layer. Then, removing the metal layer and forming a source/drain electrode on the metal-Silicon, metal-Germanium or metal-SiliconGermanium layer. A third improvement includes forming a layer of a Group IV and/or Group VI element over a III-V channel layer, and, annealing to dope the III-V channel layer with Group IV and/or Group VI species. A fourth improvement includes a passivation and/or dipole layer formed over an access region of a III-V device.
