1. An apparatus, comprising:
- a semiconductor substrate; and
one or more fins of a multi-gate transistor device coupled with the semiconductor substrate, the one or more fins comprising a gate region, a source region, and a drain region, the gate region being disposed between the source and drain regions, wherein the gate region of the one or more fins comprises a semiconductor material, and wherein the source and drain regions of the one or more fins comprise a metal portion and a semiconductor portion, the metal portion being coupled to the semiconductor portion on a surface of the semiconductor portion that is not coupled to the semiconductor substrate, and the metal portion not being coupled to the semiconductor substrate.

Abstract
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.
