Abstract:
1. A method of manufacturing an image sensor, the method comprising: forming first electrodes on a substrate; coating a patternable first photoelectric conversion material on the first electrodes; forming a first photoelectric conversion unit in a first pixel by exposing the patternable first photoelectric conversion material and removing the patternable first photoelectric conversion material of a first area excepting for the first pixel using a first mask to form a resultant structure, wherein the first photoelectric conversion unit converts a first color beam into a first electric signal; coating a patternable second photoelectric conversion material on the resultant structure including the first photoelectric conversion unit; forming a second photoelectric conversion unit in a second pixel by exposing the patternable second photoelectric conversion material and removing the patternable second photoelectric conversion material of a second area excepting for the second pixel using a second mask, wherein the second photoelectric conversion unit converts a second color beam into a second electric signal; and stacking a second electrode on the first photoelectric conversion unit and the second photoelectric conversion unit.
