Pixel design and photodiode process technology for image sensor applications

Image sensor is device that is widely used for many kinds of applications, as well as mobile phone camera and digital Still camera. The pixel scheme and the required key characteristics can vary depending on the application, and it is important to fabricate the optimal photodiode for the best image quality of the sensor. In this paper, we will explain key factors and techniques of fabricating photodiode, and introduce this factors and techniques as they apply to the actual products.
