Abstract:
1. A method of manufacturing a floating gate, the floating gate manufacturing method comprising the steps of: forming a tunneling oxide film on a substrate; forming a polymer electrolytic film on the tunneling oxide film; forming a nano-particle layer in which a number of the nano-particles are formed on the polymer electrolytic film; and repeatedly forming the polymer electrolytic film and the metal nano-particles by at least one time; wherein the step of forming the nano-particles on the polymer electrolytic film comprises: preparing a solution in which a number of nano-particles having a charge polarity reverse to that of the polymer electrolytic film are dispersed; and dipping the substrate in which the polymer electrolytic film is formed into the solution or spin coating to self-assemble the number of nano-particles on the polymer electrolytic film.
