1. A method comprising: forming a first group and a second group of fins extending above a shallow trench isolation (STI) layer, the STI layer surrounding at least a portion of the first group and second group of fins; forming a gate over the first and second groups of fins; forming a gate spacer on each side of the gate; subsequent to forming the gate spacer on each side of the gate, forming a raised source/drain (S/D) region proximate to each spacer on each fin of the first and second groups of fins, each raised S/D region having a top surface, vertical sidewalls, and an undersurface; forming a liner atop and between each raised S/D region; removing the liner from the top surface of each raised S/D region and from in between the second group of fins; subsequent to removing the liner, forming an overgrowth region on the top surface of each raised S/D region; subsequent to forming the overgrowth region on the top surface of each raised S/D region, forming an interlayer dielectric (ILD) over and between the raised S/D regions; and forming a contact through the ILD, down to the raised S/D regions.
