Abstract:
PURPOSE: A nano template and a manufacturing method thereof are provided to produce a nano template with pores having a controlled aspect ratio by efficiently controlling the size of the pores. CONSTITUTION: A nano template comprises a substrate(30), a pattern layer(10), a deposition layer(20), and a protective layer. The pattern layer is formed on the substrate from oxide of metal selected from the group consisting of Al, Ti, Ta, Zr, Nb, and W and has pores(50) including an opening exposed on the surface of the pattern layer. The deposition layer is laminated on the surface of the pores in order to reduce the pores exposing the surface of the substrate. The protective layer includes polystyrene, paraffin wax, or nail polish and fills in the pores by covering the pattern layer on the opposite side of the substrate.

Abstract:
A method for forming a floating gate, a non-volatile memory device, and a manufacturing thereof are provided to prevent a property change of layer quality due to a high-temperature heat treatment process by forming a nano crystal with a micell. A tunneling oxide layer(11) is formed on an upper surface of a semiconductor substrate(10). A nano structure is formed on the tunneling oxide layer by using a self-assembly method. A gate forming solution including a micell template is coated on the nano structure. A precursor material for synthesizing metal salt is introduced into the nano structure. A floating gate is formed by arranging the metal salt on the tunneling oxide layer by removing the micell template on the semiconductor substrate.
