Abstract

An image pickup device includes: a first electrode film; an organic photoelectric conversion film; a second electrode film; and a metal wiring film electrically connected to the second electrode film, the first electrode film, the organic photoelectric conversion film, and the second electrode film all provided on a substrate in this order, and the metal wiring film coating an entire side of the organic photoelectric conversion film.

First claim

What is claimed is:

1. An image pickup device comprising:
a plurality of first electrode films formed on a substrate;
a continuous organic photoelectric conversion film configured to convert light into electrical charge, wherein the organic photoelectric conversion film is substantially parallel to the substrate and is formed above the plurality of first electrode films;
a continuous second electrode film substantially parallel to the substrate;
a metal wiring film electrically connected to the second electrode film; and
a protective film coating at least one of a side surface of the organic photoelectric conversion film and a side surface of the second electrode film, wherein the plurality of first electrode films, the organic photoelectric conversion film, and the second electrode film are provided above the substrate in this order, and wherein a portion of the protective film is between a portion of the metal wiring film and a portion of the organic photoelectric conversion film.

2. The image pickup device according to claim 1 , wherein the metal wiring film is made of W, Al, Ti, Mo, Ta, Cu, an alloy containing one or more thereof, or a material containing one or more thereof and Si.

3. The image pickup device according to claim 1 , wherein the protective film is a silicon nitride film, a silicon nitrogen oxide film, an aluminum oxide film, or a stacked film containing two or more thereof.

4. The image pickup device according to claim 1 , wherein the protective film includes a first protective film and a second protective film, the first protective film coating an upper surface of the second electrode film, and the second protective film coating the organic photoelectric conversion film and the first protective film.

5. The image pickup device according to claim 1 , wherein the protective film has one or more openings positioned opposite the second electrode film, and the metal wiring film makes contact with the second electrode film via the one or more openings.

6. The image pickup device according to claim 1 , wherein the plurality of first electrode films correspond to a plurality of pixel electrodes provided in respective pixels, and the metal wiring film coats an entire side of the second electrode film.

7. An electronic apparatus comprising:
an image pickup device including:
a plurality of first electrode films formed on a substrate,
a continuous organic photoelectric conversion film configured to convert light into electrical charge, wherein the organic photoelectric conversion film is substantially parallel to the substrate and is formed above the plurality of first electrode films,
a continuous second electrode film substantially parallel to the substrate,
a metal wiring film electrically connected to the second electrode film, and
a protective film coating at least one of a side surface of the organic photoelectric conversion film and a side surface of the second electrode film, wherein the plurality of first electrode films, the organic photoelectric conversion film, and the second electrode film are provided above the substrate in this order, and wherein a portion of the protective film is between a portion of the metal wiring film and a portion of the organic photoelectric conversion film; and

a lens configured to cause external light to enter the image pickup device.

8. The electronic apparatus according to claim 7 , wherein the metal wiring film is made of W, Al, Ti, Mo, Ta, Cu, an alloy containing one or more thereof, or a material containing one or more thereof and Si.

9. The electronic apparatus according to claim 7 , wherein the protective film is a silicon nitride film, a silicon nitrogen oxide film, an aluminum oxide film, or a stacked film containing two or more thereof.

10. The electronic apparatus according to claim 7 , wherein the protective film includes a first protective film and a second protective film, the first protective film coating an upper surface of the second electrode film, and the second protective film coating the organic photoelectric conversion film and the first protective film.

11. The electronic apparatus according to claim 7 , wherein the protective film has one or more openings positioned opposite the second electrode film, and the metal wiring film makes contact with the second electrode film via the one or more openings.

12. The image pickup device according to claim 7 , wherein the plurality of first electrode films correspond to a plurality of pixel electrodes provided in respective pixels, and the metal wiring film coats an entire side of the second electrode film.
