Abstract:
The present invention relates to a unipolar resistance random access memory device comprising a bottom electrode; an oxide layer on the bottom electrode; and a top electrode on the oxide layer, wherein at least one insulation nanostructure is formed at an interface between the bottom or the top electrode and the oxide layer.
Abstract:
PURPOSE: A nanostructure of a block copolymer is provided to reduce a pattern resolution to about 10nm or less and to improve line edge roughness of a pattern by controlling a difference between at least two solybility parameters(δ) of block structure units in a predetermined range. CONSTITUTION: A block copolymer nanostructure(20) comprises a self-assembled block copolymer on a substrate(10), and the block copolymer comprises multiple block structure units. A difference of solybility parameters(δ) of at least two of the block structure units is equal to or greater than 5 MPa1/2. The block copolymer has a Flory-Huggins interaction parameter(χ) that is equal to or greater than 0.7. A manufacturing method of the block copolymer nanostructure comprises the following steps: (a) forming a block copolymer thin film on a substrate; (b) performing a solvent annealing process to form a pattern on the thin film; and (c) performing a plasma treatment on the pattern to remove other block structure units than the block structure units that form the pattern, thereby manufacturing a nanostructure.
