Fabrication Process of High Performance Organic Photodiode Array for Full Color Imaging

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.
