Abstract:
A manufacturing method of carbon nanotube transistors, comprising the steps of:forming an insulating layer on a substrate; forming a first oxide layer on the insulating layer by the spin-on-glass (SOG) method; forming a second oxide layer on the first oxide layer by the SOG method; forming a blind hole on the second oxide layer by exposing, developing, and etching, the blind hole exposing the insulating layer, the first oxide layer, and the sidewall of the second oxide layer; forming a carbon nanotube inside the blind hole, both ends of the carbon nanotube connecting to the opposite sidewalls of the first oxide layer; and forming a source and a drain on the second oxide layer, the source and the drain being separated by the blind hole and connecting to the two ends of the carbon nanotube, respectively.
