Abstract:
PURPOSE: A nanofiber environment filter is provided to maximize a non-surface area by laminating a functional nanofiber film to a plurality of layers, and to eliminate bio microorganism of a nano-unit and several environmental harmful gases at the same time. CONSTITUTION: A nanofiber environment filter(100) comprises a porous substrate(110) and a plurality of nanofiber films(120,130,140) which is laminated on a substrate having the respective responsivity on a plurality of materials; the porous substrate which is formed from porous ceramic, porous alumina or a porous semiconductor. The nanofiber film comprises nanofiber having high sensibility to different kinds of materials which are laminated by electrospinning to a double layer. The nanofiber film comprises organic nanofiber, organic/inorganic complex nanofiber, oxide nanofiber, carbon fiber or carbon/organic complex nanofiber.
Abstract:
A flexible substrate separating device is provided to separate a flexible substrate using a thin thread. A flexible substrate separating device comprises a horizontal unit, a supporting substrate contacting unit, a pulley and its fixture, a solvent applying unit and a wheel. The horizontal unit(203) is connected to the one end of a handle(201) and a supporting substrate in a parallel. The supporting substrate contacting unit(205) is branched into two portions at the other end of the horizontal unit. The distance of the branched portions is farther than the horizontal length of the flexible substrate adhering to the top of the supporting substrate. The end parts of the branched portions are connected to each other by a thin thread. The pulley(211) and its fixture(209) are formed on a bobbin(207), the horizontal unit and supporting substrate contacting unit in order to induce the thin thread drawn from the bobbin to the end part of the supporting substrate contacting unit.
Abstract:
An environmental gas sensor employing a nano-crystal composite oxide thin film and a manufacture method thereof are provided to show high-sensitivity, high-selectivity, long-term stability and low power-consumption. A method for manufacturing an environmental gas sensor(100) employing a nano-crystal composite oxide thin film comprises the following steps of: forming a metal electrode(120) on a substrate(110); and growing different sort of oxide nano-crystal particles on the metal electrode to form a nano-crystal composite oxide thin film(140). The growth of the different sort of oxide nano-crystal particles is performed by a pulsed laser deposition method or a sputter method using a different kind of oxide ceramic target. The step of forming the nano-crystal composite oxide thin film is performed in the temperature range of room temperature to 800°C.
Abstract:
A method for manufacturing a thin film transistor of multi-layered structure and an active matrix display device including the same are provided to lessen a leakage current of a TFT device by forming a gate metal layer with an etched corner area. A buffer insulating layer(120) is formed on a plastic substrate(110). A silicon layer is formed on the buffer insulating layer, and then the silicon layer is patterned to form an active layer(130). A gate insulating layer is formed on the active layer, and then plural gate metal layers(150) are deposited on the gate insulating layer. The plural gate metal layers are patterned, and then a corner area of the lowermost gate metal layer formed on the gate insulating is etched.
