Abstract:
PURPOSE: A method for manufacturing a stamp with a micro/nano hybrid pattern is provided to prevent the deformation and the damage of the stamp by forming patterns based on the irradiation of and electron beam and light with respect to a metal-organic precursor composition and washing a developer. CONSTITUTION: A metal-organic precursor composition based on organic ligand is coated on a substrate for a stamp(S1). Electron beam and light are locally irradiated to the composition. A developer is washed to form a micro/nano hybrid patterned metal oxide thin film pattern(S2). The pattern is heated or undergoes microwave, X-ray, gamma-ray, or ultraviolet ray irradiation or plasma treatment in order to change one of the shape, the line width, and the height of the pattern(S3).
Abstract:
PURPOSE: A method for manufacturing a semiconductor device for substrate reuse is provided to improve productivity of the semiconductor device by securing two thin film structures with one separation process. CONSTITUTION: A first device layer(320) is formed at one side of a substrate(300). The first device layer comprises a transparent electrode layer and a p-type electrode. A second device layer(340) is formed at the other side of the substrate. A first carrier substrate(360) is welded to the first device layer. A second carrier substrate(380) is welded to the second device layer. The first device layer and the substrate are separated and the second device layer and the second device layer are separated through a laser lift off method.

PURPOSE: An organic solar cell and a manufacturing method thereof are provided to improve solar cell efficiency by increasing an interfacial area of an electron donor layer and an electron accepting layer by adding a regular pattern to PN junction. CONSTITUTION: An anode(120) is formed on a transparent substrate(110). A regular pattern(123) is formed on an upper side of the anode. An electron accepting layer(130) is formed on the anode. A regular pattern(133) is formed on an upper side of the electron accepting layer. An electron donor layer(140) is formed on the electron accepting layer. A cathode(150) is formed on the electron donor layer.
Abstract:
PURPOSE: A graphene thin film in which a pattern is formed is provided to improve adhesive force with a high position film by including dangling bond and a chemical functional group in the unevenness part of a graphene layer. CONSTITUTION: A graphene thin film comprises a graphene layer(210) and a chemical functional group(220). Concavo-convex is formed on the surface of the graphene layer. The density of edge part is increased when the concavo-convex is formed on the surface of the graphene layer. The chemical functional group is formed on the surface of the graphene layer. The chemical functional group is more than one among phenol, carbonyl, carboxyl, quinine, and lactone.
