Sony patents camera sensor design to reduce color mixing
Sony describes an imaging device that uses two layers of light-blocking material to separate pixels on a camera sensor. One layer sits between the pixels, while a second layer is placed inside the transparent electrode layer with small gaps to improve light control.
In the filing’s own words
[Problem] To provide an imaging device capable of suppressing color mixing and an electronic apparatus using the imaging device. [Solution] An imaging device of the present disclosure includes a photoelectric conversion layer disposed on a semiconductor substrate, a transparent electrode layer disposed on the photoelectric conversion layer, a first light-shielding portion that separates the photoelectric conversion layer into a plurality of pixels arranged in a first direction and a second direction that intersects the first direction, and is disposed along a boundary between the separated pixels, and a second light-shielding portion disposed along the boundary between the separated pixels inside the transparent electrode layer and disposed so that a portion of the boundary between adjacent pixels is interrupted.
What exactly they claim (claim 1)
1. An imaging device comprising: a photoelectric conversion layer disposed on a semiconductor substrate; a transparent electrode layer disposed on the photoelectric conversion layer; a first light-shielding portion that separates the photoelectric conversion layer into a plurality of pixels arranged in a first direction and a second direction that intersects the first direction, and is disposed along a boundary between the separated pixels; and a second light-shielding portion disposed along the boundary between the separated pixels inside the transparent electrode layer and disposed so that a portion of the boundary between adjacent pixels is interrupted.
