Abstract: An image sensor includes a substrate, a plurality of photodiodes in the substrate, a pixel separating pattern in the substrate separating the plurality of photodiodes, a first active pattern in the substrate at least partially overlapping a first photodiode and a second photodiode from among the plurality of photodiodes, a selection gate on the first active pattern at least partially overlapping the first photodiode, and a source follower gate on the first active pattern at least partially overlapping the second photodiode. The first photodiode is adjacent to the second photodiode. The pixel separating pattern includes a first pixel separating pattern and a second pixel separating pattern disposed between the first photodiode and the second photodiode. The first pixel separating pattern is spaced from the second pixel separating pattern. The first active pattern includes a first extrinsic region disposed between the first pixel separating pattern and the second pixel separating pattern.

Abstract: An image sensor includes: a substrate including a first side configured to receive light and a second side that is opposite the first side; a pixel separating pattern configured to at least partially define a unit pixel in the substrate; a first photoelectric conversion layer and a second photoelectric conversion layer arranged in a first direction in the pixel separating pattern; a first separating pattern configured to at least partially define the first photoelectric conversion layer and the second photoelectric conversion layer in the substrate between the first photoelectric conversion layer and the second photoelectric conversion layer; a first grid pattern on the pixel separating pattern; and a second grid pattern on the first separating pattern and having a lower height than the first grid pattern.

Abstract: An image sensor is provided. The image sensor includes: a pixel array including first and second pixel groups, each of which includes unit pixels arranged in 4×4 array, each of the unit pixels including a photodiode provided, and the first and second pixel groups being alternately disposed in multiple directions; a logic circuit configured to acquire pixel signals from the unit pixels; first microlenses provided on corresponding unit pixels in the first pixel groups; and second microlenses provided on four corresponding unit pixels of the unit pixels included in the second pixel groups. Each of the first and second pixel groups includes a device isolation layer provided between the unit pixels, and a color filter provided on the first surface, and each of the second pixel groups includes an overflow region configured to move electrical charges between adjacent photodiodes.
