dc.description.abstract	As interest in applications in biomedicine, education, environmental monitoring, optical communications, pharmaceutics and machine vision grows, interest in image sensors are growing. However, in order to apply the image sensor to various applications, there are many limitations such as the thick thickness of Si (>3 ㎛), the need for color filters for the color selectivity, and insufficient mechanical properties. Organic semiconductors are a very attractive material to cover these problems. In this paper, we present the mechanism and manufacturing process of color-selective photodiode using organic semiconductor.	-

dc.description.alternativeAbstract	본 논문은 기존 무기물 기반 이미지센서가 가지는 색선택성, 높은 공정비용, 두꺼운 두께등의 문제를 해결하기 위해서 색 선택성 유기 반도체를 사용하여 유기 포토 다이오드 어레이를 제조하는 방법에 대한 논문입니다. 우선 유기반도체를 사용한 색 선택성 방법의 경우 두가지를 제시하였습니다. 첫번째는 선택성 여기자 추출 방법으로 두께에 따라 흡광이 달라지는 유기반도체의 특성을 이용하여 선택적으로 흡광을 조절하는 방법입니다. 각 P 형과 N 형 반도체의 두께를 선택적으로 조절하고 여기자를 추출하는 위치를 조절하여 색 선택성을 구현하였고 이를 통해 적색광, 녹색광, 청색광 광 다이오드를 구현하였습니다. 두번째는 유기 반도체가 가지는 흡광을 이용하는 방법으로 유기 반도체의 에너지 밴드 조절을 통해서 특정 영역의 빛을 흡수하는 유기반도체를 합성을 하고 이를 이용하여 선택적인 흡광을 얻을 수 있었습니다. 또한 공정 비용을 줄이고 대면적 박막형성이 가능한 용액공정을 이용하여 패턴을 형성하기 위해서 계면활성제를 이용한 용해도 변환 공정을 제시하였습니다. 기존 용액공정을 통해서 두개 이상의 패턴을 형성할 경우 기 형성된 패턴이 용액의 용매에 영향을 받는 문제가 존재했습니다. 이를 해결하기 위해서 계면활성제를 이용해 용해도를 일시적으로 변경 가능한 기술을 개발 하였으며 이를 통해서 높은 정밀도를 가지는 패턴 형성 기술을 선보였습니다. 상기 개발된 색선택성을 위한 기술 및 용액 공정을 위한 용해도 변환 공정의 경우 용액 공정을 통한 유기 이미지센서 및 유기 광전기기에 필수적인 기술입니다. 이는 발전하는 현대 유기 광전기기의 성장에 큰 도움이 될 것으로 예상됩니다.	-
