PHOTO DIODE AND METHOD OF FORMING THE SAME

摘要

Provided in the present invention is a method for forming photodiodes. The method comprises the steps of: forming a first lower electrode corresponding to a first pixel and a second lower electrode corresponding to a second pixel on a substrate; forming a dielectric layer on the substrate; patterning the dielectric layer on the substrate; forming a photo conversion layer on the substrate; forming an upper electrode on the photo conversion layer; and forming a color filter layer on the upper electrode. A part of the dielectric layer separates a first part of the color filter layer corresponding to the first pixel from a second part of the color filter layer corresponding to the second pixel, and a refractive index of the dielectric layer is a refractive index of the color filter layer or less.
