Abstract
Embodiments herein describe FETs with channels connected on the sides to a metal liner. To avoid the difficulties of connecting the sides of the channels to metal liners for the drain and source regions, the embodiments herein form a male/female contact between the channels and the metal liners. In one embodiment, instead of exposing only the end or side surfaces of the channels, an end knob of the channel is exposed. This knob can include the side surface as well as a portion of the top, bottom, front, and back sides of the channel. As such, when the metal liner is deposited on the knob, this metal forms an electrical connection on all sides of the knob. This male/female connection provides a more reliable and lower resistance connection between the channel and the metal liner than using only the end or side surfaces of the channel.
