  • Electronic device and method for manufacturing electronic device
    Patent number: 11950522
    Abstract: A method for manufacturing an electronic device including a semiconductor memory may include forming a first carbon electrode material, surface-treating the first carbon electrode material to decrease a surface roughness of the first carbon electrode material, and forming a second carbon electrode material on the treated surface of the first carbon electrode material. The second carbon electrode material may have a thickness that is greater than a thickness of the first carbon electrode material.

  • Metal oxide nano powder and manufacturing method of the same
    Patent number: 8038979
    Abstract: Disclosed is a method of manufacturing a metal oxide nano powder comprising preparing a first dispersed solution by adding a nano-sized metal powder to water and dispersing the metal powder within the water, performing a hydration reaction of the first dispersed solution at a temperature of about 30 to about 70° C. to generate a precipitation, and filtering and drying the precipitation to prepare a metal oxide powder. Also, disclosed is a metal oxide nano powder manufactured by the method described above, and having any one of a bar-form, a cube-form, and a fiber-form.

  • METHOD AND APPARATUS FOR MANUFACTURING METAL NANO-PARTICLES USING ALTERNATING CURRENT ELECTROLYSIS
    Publication number: 20110068013
    Abstract: Disclosed herein are a method and apparatus for preparing metal nanoparticles using alternating current (AC) electrolysis, in which the yield of metal nanoparticles obtained can be greatly improved by maintaining the concentrations of a reducing agent and a dispersing agent at constant levels in proportion to the intensity of an electric current during the production of the metal nanoparticles.
