Abstract:
1. A method for forming a self-aligned carbon-nanotube field effect transistor semiconductor device comprising the steps of: depositing a nanotube on a thermal oxide substrate, wherein the substrate includes an alignment mark; forming a metal contact at each end of the nanotube, wherein a first metal contact is a source contact and a second metal contact is a drain contact; depositing an amorphous silicon layer over the source contact, the drain contact, and the nanotube; oxidizing the amorphous silicon; forming nitride spacers on opposing sides of each of the metal contacts; depositing a high k dielectric film over the oxidized amorphous silicon and the nitride spacers; and forming a gate substantially between the source contact and the drain contact, and over the nanotube.
