Claim Text:
1. A non-planar field effect transistor (FET), comprising: a semiconductor substrate of a first conductivity type and having a first surface, wherein the semiconductor substrate is formed with a cavity having a recessed surface, wherein the cavity has an upper portion bounded by a sidewall extending downwardly from the first surface and a lower portion extending under the sidewall adjacent the recessed surface; a first doped region of a second, opposite, conductivity type located adjacent the first surface and adapted to act as a source or drain; a second doped region of the second conductivity type located on the recessed surface and extending laterally into the semiconductor substrate directly under the first doped region, adapted to act as a drain or a source, and coupled to the first doped region by the sidewall of the semiconductor substrate; a gate insulator on the sidewall; and a gate conductor on the gate insulator and overlying a part of the second doped region.
