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 an amorphous silicon pillar over each end of the nanotube; isolating the amorphous silicon pillars with a layer of oxide; forming a gate dielectric layer between the amorphous silicon pillars; forming a gate substantially between the amorphous silicon pillars and over the nanotube; forming an etch resist over the gate; replacing the amorphous silicon with a plurality of metal contacts, wherein a first metal contact is a source and a second metal contact is a drain; and depositing a passivation dielectric over the device.
