Abstract:
1. A carbon nanotube memory device, comprising: a substrate; a source electrode and a drain electrode arranged with a predetermined interval between them on the substrate and subjected to a voltage; a carbon nanotube connecting the source electrode to the drain electrode and serving as a channel for charges; a memory cell, located over the carbon nanotube, that stores charges from the carbon nanotube, the memory cell including: a first insulating film formed in contact with the upper surface of the carbon nanotube; a charge storage film, deposited on the first insulating film, that stores charges; and a second insulating film formed on the charge storage film and contacting the gate electrode, wherein a thickness of the second insulating film is approximately double a thickness of the charge storage film; and a gate electrode, formed in contact with the upper surface of the memory cell, for controlling the amount of charge flowing from the carbon nanotube into the memory cell.
