Abstract:
An image sensor and a forming method thereof are disclosed. The image sensor includes: a semiconductor substrate, the semiconductor substrate has photodiodes therein; and a dielectric layer, the dielectric layer is located on a surface of the semiconductor substrate; and photoelectric conversion films formed in the dielectric layer, wherein the photoelectric conversion films are in one-to-one correspondence aligned with the photodiodes, so that light passing through the photodiodes is transmitted to the corresponding photoelectric conversion films. The solution provided in the present disclosure can effectively improve the quantum efficiency of the image sensor. The photoelectric conversion films are made of organic photoelectric materials. The photoelectric conversion films have photosensitive area, which is equal or larger than the photosensitive area of the corresponding photodiode.

Claim (Index 7):
A method of forming an image sensor, comprising:\n providing a semiconductor substrate, having a plurality of photodiodes on the first surface of the semiconductor substrate; forming a dielectric layer on the first surface of the semiconductor substrate; and forming a plurality of photoelectric conversion films in the dielectric layer; wherein the plurality of photoelectric conversion films each is in one-to-one correspondence aligned to one of the plurality of photodiodes, so that light passing through each of the plurality of photodiodes is transmitted to the corresponding photoelectric conversion film.
