Abstract: An integrated circuit, IC, (1001) is provided. The IC includes a substrate (210) that includes first and second laterally adjacent channels (1002). A shared source or drain (220) region is between the first and second channels. The shared source or drain region includes an uppermost surface and further includes a second surface (320) recessed from the uppermost surface and sidewalls extending from the uppermost surface to the second surface to define a recess (711). First and second gate structures (250) including gate metal are disposed on the first and second channels. An S/D wrap-around contact, WAC, (710) includes a first portion which extends into the recess to contact the second surface and the sidewalls and is wrapped around the S/D region at an exterior of the recess in a cross section perpendicular to channel direction.
