1. A device comprising:
a first protrusion disposed on a substrate, the first protrusion formed of a semiconductor material;
a first silicon-containing channel region disposed on a first portion of the first protrusion
a first gate structure wrapping around the first silicon-containing channel region;
a first source/drain feature disposed on a second portion the first protrusion; and
a second silicon-containing channel region disposed on a third portion of the first protrusion;
a second gate structure wrapping around the second silicon-containing channel region;
a first electrical barrier layer disposed under and interfacing with the first source/drain feature, the first silicon-containing channel region and the second silicon-containing channel region such that the first electrical barrier layer extends continuously from first silicon-containing channel region to the second silicon-containing channel region.
