    Abstract: An image sensor includes: a substrate, having first and second surfaces opposing each other in a first direction, on which a plurality of unit pixels are arranged, the plurality of unit pixels including a normal pixel, an autofocusing pixel, and a compensation pixel in a direction, parallel to the first surface; a photodiode disposed in the substrate in each of the plurality of unit pixels; and a device isolation layer disposed between the plurality of unit pixels. The unit pixels include color filters, separated from each other by a grid, and microlenses disposed on the color filters. The compensation pixel is disposed on one side of the autofocusing pixel and includes a compensation microlens, smaller than a normal microlens included in the normal pixel, and a transparent color filter separated from adjacent color filters by a compensation grid smaller than a normal grid included in the normal pixel.

    Abstract: An image sensor includes a substrate having a first surface and a second surface opposite to each other in a first direction, and a pixel array including a plurality of pixels arranged in a second direction perpendicular to the first direction and a third direction perpendicular to the second direction. The pixel array includes a first pixel and a second pixel adjacent to the first pixel. Each of the first pixel and the second pixel is inside the substrate and includes a pair of photodiodes. The first pixel includes a first pixel interior separation layer between the pair of photodiodes and extending in the first direction. The second pixel includes a second pixel interior separation layer between the pair of photodiodes and extending in the first direction.
