Abstract: Disclosed herein are PN-body-tied field effect transistors (PNBTFETs), as well as related devices and methods. In some embodiments, an integrated circuit (IC) structure may include: a fin including a channel region, a contact region, and an intermediate region between the contact region and the channel region, wherein the channel region includes a dopant of a first type, the intermediate region includes a dopant of a second type different from the first type, and the contact region includes a dopant of the first type; a gate that at least partially wraps around the channel region; and a conductive contact in contact with the contact region.
