    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 first photodiode group, a second photodiode group, a first transfer transistor group, a second transfer transistor group, a floating diffusion region of a substrate in which electric charges generated in the first photodiode group are stored, and a power supply node for applying a power supply voltage to the second photodiode group. A barrier voltage is applied to at least one transfer transistor of the second transfer transistor group. The power supply voltage allows electric charges, generated in the second photodiode group, to migrate to the power supply node, and the barrier voltage forms a potential barrier between the second photodiode group and the floating diffusion region.

    Abstract: An image sensor includes a normal pixel, a first auto-focus (AF) pixel, and a second AF pixel, each of the normal pixel, the first AF pixel and the second AF pixel including a photodiode. The image sensor further includes a normal microlens disposed on the normal pixel, and a first AF microlens disposed on the first AF pixel and the second AF pixel. The photodiode of the normal pixel, the photodiode of the first AF pixel, and the photodiode of the second AF pixel are respectively disposed in photo-detecting areas of a semiconductor substrate. A height of the first AF microlens in a vertical direction from a top surface of the semiconductor substrate is greater than a height of the normal microlens in the vertical direction from the top surface of the semiconductor substrate.

    Abstract: An image sensor includes: a chip structure including normal pixels and auto focus pixels; a grid structure disposed on the chip structure; and color filter regions defined by the grid structure over the chip structure. The color filter regions include normal filter regions and auto focus filter regions. The normal filter regions correspond to the normal pixels. The chip structure includes a first region at a first distance, and a second region a second distance greater than the first distance. The auto focus filter regions include a first auto focus filter region on the first region and a second auto focus filter region on the second region. A first width of a first grid portion disposed adjacent the first auto focus filter region among the grid structure is narrower than a second width of a second grid portion disposed adjacent the second auto focus filter region among the grid structure.
