Patent ID: 8063451

Claim:
A self-aligned nano field effect transistor, comprising: a substrate; a one-dimensional conductive nano material comprising a first end, a second end, and a middle portion; a source electrode layer formed on the substrate and the first end of the one-dimensional conductive nano material, wherein the source electrode layer is elevated above the substrate and the middle portion of the one-dimensional conductive nano material, wherein the source electrode layer comprises a first upper surface and a first side wall; a drain electrode layer formed on the substrate and the second end of the one-dimensional conductive nano material, wherein the drain electrode layer is elevated above the substrate and the middle portion of the one-dimensional conductive nano material, wherein the drain electrode layer comprises a second upper surface and a second side wall; a gate dielectric layer formed on the first upper surface and the first side wall of the source electrode layer, the second upper surface and the second side wall of the drain electrode layer, and the middle portion of the one-dimensional conductive nano material; and a gate electrode layer on the gate dielectric layer, wherein the gate electrode layer comprises a first portion over the middle portion of the one-dimensional conductive nano material, wherein the first portion of the gate electrode layer is below the first upper surface of the source electrode layer and the second upper surface of the drain electrode layer.
