Abstract
Embodiments of the invention are directed to a method of forming a semiconductor device. A non-limiting example of the method includes performing fabrication operations to form a field effect transistor (FET) device on a substrate. The fabrication operations include forming a channel region over the substrate, forming a bottom conductive layer of a wrap-around source or drain (S/D) contact over the substrate, and forming a S/D region over the bottom conductive layer and adjacent to the channel region. The S/D region is communicatively coupled to the channel region and the bottom conductive layer.
