the present invention is a carbon nanotube field emission device manufacturing method as the film (membrane) in the form of nano-porous alumina creating a frame bonded to hydrogen bond to the silicon wafer surface and to increase the temperature in the state under pressure and bonded to a silicon wafer with nano framework with ether bond, an extension of the diameter of the pores of the nano-frame junction were formed in the pore The development of technologies for producing carbon nanotube field emission device made by using a metal nanoparticle catalyst. ; said bonded alumina after filling the other metal ion concentration in the pore solution and the acid solution was extended with the diameter of the pores of the nano-mold by evaporation of a predetermined size and a nanoparticle catalyst in the form is prepared, and a method for controlling the diameter of the carbon nanotubes by using this. ; application of the carbon nanotube as an electron emission source of field emission devices of the tip to form an excellent field emission device can be implemented.
