A self-aligned field-effect transistor (FET) is provided. The self-aligned FET includes a substrate, a dielectric layer, conductive electrodes, and a carbon nanotube. A patterned back-gated conductive electrode is disposed in the substrate. The dielectric layer is disposed on the substrate. The conductive electrodes are disposed on the dielectric layer and function as a source/drain. The patterned source/drain conductive electrodes contain a metal silicide such as cobalt silicide serve as a catalyst for carbon nanotube synthesis. The carbon nanotube is disposed on the dielectric layer to be electrically connected with the source/drain conductive electrodes.
