나노렌즈어레이몰드의 제조방법 및 그 방법에 의해 제조된 몰드를 이용한 나노렌즈어레이의 제조방법이 개시된다. 본 발명의 나노렌즈어레이몰드의 제조방법은, 실리콘 기판을 산화시켜 표면에 1차 실리콘 산화막을 형성하고, 1차 실리콘 산화막 상에 반사 방지층과 감광층을 차례로 형성하는 단계; 감광층에 규칙적인 배열을 갖는 미세패턴을 포토리소그래피에 의해 형성하고,형성된 미세패턴에 따라 노출된 반사 방지층을 제거하는 단계;감광층을 마스크로 건식 식각하여 1차 실리콘 산화막을 선택적으로 제거하는 단계; 및 선택적으로 제거된 1차 실리콘 산화막을 마스크로 실리콘 기판을 건식 식각하여 미세패턴을 형성하는 단계; 1차 실리콘 산화막을 제거하는 단계;미세패턴이 형성된 실리콘 기판에 열산화 공정을 수행하여 미세패턴 상에 2차 실리콘 산화막을 형성하는 단계; 및상기 2차 실리콘 산화막을 제거하는 단계를 포함한다. 이에 의하여, 나노렌즈 형상 조절이 매우 간단하고, 이에 의해 제조된 나노렌즈어레이는 나노수준의 미세한 렌즈들의 배열임에도 렌즈의 형태가 매우 균일하고 표면이 매끄러워 광학적 특성이 우수하다.
Abstract:
PURPOSE: A sprayed particle trace forming device and a collision force analysis system including thereof are provided to form a trace of a sprayed particle without measuring the sprayed particle directly, and to compute magnitude of a collision force accurately by measuring and producing the trace. CONSTITUTION: A trace forming device comprises a substrate (110) and a spray nozzle (120). The substrate is comprised to form a concave trace due to a collision with a particle sprayed from the spray nozzle. The spray nozzle sprays the particle to one side of the substrate.

PURPOSE: A method for manufacturing a silicon nanotip array and a silicon nanotip array manufactured by the same are provided to freely form the shape and the arrangement of initial mask patterns and to control the shape and the arrangement of nanotips. CONSTITUTION: An antireflection layer and a photoresist layer are successively formed on a silicon oxide layer formed by oxidizing a silicon substrate(step a). A micro pattern is regularly formed on the photoresist layer(step b). A dry etching process is performed by using the photoresist layer as a mask to selectively remove the silicon oxide layer(step c). A dry etching process is performed by using the silicon oxide layer as a mask to form a nanotip(step d). The silicon oxide layer is removed(step e).

Abstract:
PURPOSE: A selective surface reforming method of a black matrix for a flat panel display and an apparatus thereof are provided to reform only an upper surface of the black matrix into a hydrophobic surface. CONSTITUTION: A hydrophobic solution is sprayed to the first and second solution transferring rollers(22,24) through a nozzle(20). According as the solution transferring rollers are rotated, the hydrophobic solution is uniformly transferred to a transfer roller(30). A hydrophilic thin film is formed on the whole surface including a black matrix. The transfer roller which is coated by the hydrophobic solution and the black matrix are contacted with each other. The hydrophobic solution is transferred to the upper part of the black matrix. The black matrix is dried through a drying device(40).
Abstract:
The present invention relates to a nanowell array biosensor on a large-sized substrate and a method for producing the same. More specifically, by means of the novel method, a nano-sized well array structure is reproducibly realized so that the detection sensitivity, selectivity, and reliability of a biomaterial can be improved. According to the present invention, a nano-sized well array structure which is highly integrated in a narrow region can be uniformly and reproducibly realized. Accordingly, a biosensor in which the detection sensitivity, selectivity, and reliability of biomolecules and biomaterials such as a variety of enzymes, proteins, and DNA are improved can be produced. Moreover, according to the present invention, in comparison to existing techniques, the biosensor can be mass produced on a large-sized substrate of 6 inches (diameter 150 mm) or larger so as to have high possibility for commercialization.
