Embodiments described include straining transistor quantum well (QW) channel regions with metal source/drains, and conformal regrowth source/drains to impart a uni-axial strain in a MOS channel region. Removed portions of a channel layer may be filled with a junction material having a lattice spacing different than that of the channel material to causes a uni-axial strain in the channel, in addition to a bi-axial strain caused in the channel layer by a top barrier layer and a bottom buffer layer of the quantum well.

A trigate device having an extended metal gate electrode comprises a semiconductor body having a top surface and opposing sidewalls formed on a substrate, an isolation layer formed on the substrate and around the semiconductor body, wherein a portion of the semiconductor body remains exposed above the isolation layer, and a gate stack formed on the top surface and opposing sidewalls of the semiconductor body, wherein the gate stack extends a depth into the isolation layer, thereby causing a bottom surface of the gate stack to be below a top surface of the isolation layer.

Reducing external resistance of a multi-gate device by incorporation of a partial metallic fin is generally described. In one example, an apparatus includes a semiconductor substrate and one or more fins of a multi-gate transistor device coupled with the semiconductor substrate, the one or more fins having a gate region, a source region, and a drain region, the gate region being disposed between the source and drain regions where the gate region of the one or more fins includes a semiconductor material and where the source and drain regions of the one or more fins include a metal portion and a semiconductor portion, the metal portion and the semiconductor portion being coupled together.
