Abstract:
1. A method of manufacturing an electronic device using a vertical carbon nanotube, comprising the steps of: (a) preparing a substrate on which a silicon source is formed; (b) forming a first insulating layer on the substrate, and etching the first insulating layer such that a top surface of the silicon source is exposed; (c) forming a second insulating layer on the silicon source, and forming a gate by patterning the second insulating layer; (d) forming a third insulating layer on the gate, and forming a through hole in which a carbon nanotube channel is to be formed by etching the third insulating layer and the second insulating layer; (e) forming a fourth insulating layer surrounding the gate on the through hole and the third insulating layer, and forming a spacer by etching the fourth insulating layer; (f) forming a metal catalyst on the silicon source; (g) vertically growing the carbon nanotube channel on the silicon source using the metal catalyst; (h) forming a fifth insulating layer on the through hole in which the carbon nanotube channel is formed and the third insulating layer; and (i) patterning the fifth insulating layer such that the carbon nanotube channel is exposed, and forming a silicon drain at the carbon nanotube channel exposed region, wherein the carbon nanotube channel is connected between the silicon source and the silicon drain.
