Abstract:
본 발명은 패턴화 FeCl 3 상의 전도성 폴리(3,4-에틸렌디옥시티오펜)(PEDOT) 박막의 선택적 증기상 증착법에 관한 것으로, 미세접촉 인쇄법(microcontact printing)에 의하여 폴리에틸렌테레프탈레이트 기판 상에 패턴화 FeCl 3 를 제조한다. 상기 패턴화 FeCl 3 가 에틸렌디옥시티오펜 단량체의 증기상 중합을 이용한, 폴리(3,4-에틸렌디옥시티오펜) 박막의 선택적 증착을 규정한다. 선택적 증기상 증착법은, 폴리(3,4-에틸렌디옥시티오펜) 박막이 오직 폴리에틸렌테레프탈레이트 기판의 FeCl 3 를 노출시키는 구역에서 선택적으로 증착된다는 관찰에 기초하고, 이는 에틸렌디옥시티오펜 단량체가 오직 산화제, 예를 들어 FeCl 3 , Fe(ClO 4 ), 및 유기 라디칼을 함유하는 유기산/무기산의 Fe(Ⅱ)의 염의 존재 하에 중합될 수 있기 때문이다. 폴리(3,4-에틸렌디옥시티오펜) 박막, 선택적 증기상 증착법, 미세접촉 인쇄법
Abstract:
A molecular layer deposition method which can substantially complement stability and permeability mentioned as problems of self-assembled monolayers, and particularly can be applied to the fields of protective films of organic electroluminescent devices, and non-volatile memories usefully. A preparing method of self-assembled monolayers repeatedly comprises the steps of: (1) forming a TiO2 layer on an SiO2 surface by using atomic layer deposition; (2) gas phase reacting a surfactant and organic silicon with molecules of organic sulfur or organic phosphoric acid by using molecular layer deposition, thereby forming self-assembled monolayers on the surface of the TiO2 layer; (3) activating functional groups of alkane chains of the formed self-assembled monolayers into -OH or -COOH using UV/O3 or O3; and (4) depositing TiO2 onto the activated self-assembled monolayers by using atomic layer deposition.
Abstract:
PURPOSE: A method for manufacturing an N type ZnO semiconductor thin film and a thin film transistor are provided to reduce manufacturing costs by depositing an insulation layer below 150 degrees centigrade and forming a ZnO thin film below 100 degrees centigrade. CONSTITUTION: A substrate(10) is arranged inside a chamber of an atomic layer deposition device. A Zn precursor is inserted into the chamber independently or with the carrier gas. An atomic layer including Zn is formed by absorbing a Zn precursor with an atomic layer deposition method. A nitrogen precursor and an oxygen precursor are respectively inserted into the chamber. An N-type ZnO semiconductor thin film(40) doped with the nitrogen is formed using a surface chemical reaction among the Zn precursor, the nitrogen precursor, and the oxygen precursor.
Abstract:
A method for selective vapor phase deposition of a PEDOT(poly(3,4-ethylenedioxythiophene)) thin film onto a FeCl3-patterned PET(polyethylene terephthalate) substrate formed by microcontact printing is provided, wherein the PEDOT thin film can be selectively deposited onto only a portion of the PET substrate that exposes FeCl3, and the vapor phase polymerization provides an ideal method for selective deposition of a conductive polymer onto a patterned catalytic film. A method for selective vapor phase deposition of a conductive PEDOT(poly(3,4-ethylenedioxythiophene)) thin film onto patterned FeCl3 comprises: a first step of forming a patterned FeCl3 catalyst layer on a PET(polyethylene terephthalate) substrate using microcontact printing; and a second step of selectively depositing the PEDOT thin film onto a FeCl3-patterned PET by vapor phase polymerization, a salt of Fe(III) being used as dopant ions relative to PEDOT, and the vapor phase polymerization being carried out in the presence of an oxidizer. A PET substrate comprises a PEDOT thin film manufactured by the method and selectively deposited thereon.

A method for patterning poly(dimethylsiloxane) stamp by using UV is provided to uniformly form diverse patterns on a variety of substrates in a short time. The method for patterning a poly(dimethylsiloxane) stamp by using UV comprises the steps of: (a) preparing a poly(dimethylsiloxane)(PDMS) stamp(3) from a master; (b) irradiating UV(254 nm) on a substrate(4) using the PDMS stamp(3) so as to form PDMS patterns; and (c) performing selective thin film deposition or wet-etching using PDMS patterns as a template. In the method, the deposition of thin film in the step(c) is performed by an atomic layer deposition, and the thin film is a thin film of titanium dioxide.
Abstract:
A method for forming a metal interconnection is provided to guarantee a simplified process by forming a low-resistive multilayered thin film of a Cu/Co structure while using an ALD or MOCVD method of a Co thin film and a Cu thin film and a micro contact printing method. Metal is deposited on a substrate by a micro contact printing method wherein OTS(octadecyltrichlorosilane) of a second pattern made of a reverse pattern of a desired first pattern is formed. A Co thin film(24) is deposited on the front surface of the substrate. A Co thin film is selectively deposited only in a region where OTS(22a) is not formed, made of the same pattern as the first pattern. The substrate region of the first pattern in which the OTS is not formed is a hydrophilic region where a nucleus can easily be generated. The substrate region of the second pattern in which the OTS is formed is a hydrophobic region where a nucleus is difficult to generate.
