Abstract:
1. A method of forming a carbon nanotube field-effect transistor, comprising: forming a first carbon nanotube film; forming a first gate structure on a surface of the first carbon nanotube film to influence an electric field of the first carbon nanotube film; forming a source contact and a drain contact on the first carbon nanotube film, wherein at least one of the source contact and the drain contact is separated from the first gate structure by an underlap region; and forming a second carbon nanotube film directly on the first gate structure, the source contact and the drain contact, wherein the first gate structure influences an electric field of the second carbon nanotube film, and wherein a bottom surface of the second carbon nanotube film is substantially coplanar with a top surface of the first gate structure, a top surface of the source contact and a top surface of the drain contact.
