Abstract
An image sensor includes: a plurality of pixels arranged in two dimensions, wherein at least one pixel among the pixels includes: a photoelectric conversion layer formed in a substrate; a color filter layer formed over the photoelectric conversion layer; a first shading layer formed in the same plane as the color filter layer and defining a first light transmitting region; and a second shading layer formed between the photoelectric conversion layer and the first shading layer and defining a second light transmitting region.
Claims18
An image sensor comprising:
- a plurality of pixels arranged in two dimensions,
- wherein at least one pixel among the pixels includes:
- a photoelectric conversion layer formed in a substrate;
- a color filter layer formed over the photoelectric conversion layer;
- a first shading layer formed in the same plane as the color filter layer and defining a first light transmitting region;
- and
- a second shading layer formed between the photoelectric conversion layer and the color filter and defining a second light transmitting region,
- wherein the second shading layer is spaced apart from the color filter in a vertical direction.

An image sensor, comprising:
- a plurality of pixels arranged in two dimensions,
- wherein the pixels include at least a pair of phase difference detecting pixels that perform a pupil division on an object light in a first direction and a second direction that are different from each other and output pupil-divided images, and
- each phase difference detecting pixel includes:
- a photoelectric conversion layer formed in a substrate;
- a color filter layer formed over the photoelectric conversion layer;
- a first shading layer formed in the same plane as the color filter layer and defining a first light transmitting region;
- and
- a second shading layer formed between the photoelectric conversion layer and the first shading layer and defining a second light transmitting region, and
- the pair of the phase difference detecting pixels includes:
- a first phase difference detecting pixel that has the first light transmitting region, defined by the first shading layer, disposed towards the first direction and has the second light transmitting region, defined by the second shading layer, disposed towards the second direction;
- and
- a second phase difference detecting pixel that has the first light transmitting region, defined by the first shading layer, disposed towards the second direction and has the second light transmitting region, defined by the second shading layer, disposed towards the first direction.
