    Abstract: A three-dimensional image sensor includes a first photoelectric converter in a first pixel region of a substrate, a second photoelectric converter in a second pixel region of the substrate, a first transfer gate structure disposed on the substrate at one side of the first photoelectric converter, a second transfer gate structure and a drain gate structure disposed on the substrate at opposite sides of the second photoelectric converter and whose gate insulating layers are thinner the gate insulating layer of the first transfer gate structure. The gate insulating layers can be fabricated by forming a first insulating layer on the pixel regions of the substrate, removing part of the first insulating layer from the second pixel region, and subsequently forming a second insulating layer on the substrate including over a part of the first insulating layer which remains on the first pixel region.

    Abstract: An image pixel includes an organic photodiode, a first electrode connected to a first voltage, and a second electrode connected to a second voltage. The first electrode and the second electrode are disposed on a first surface of the organic photodiode, and a read-out circuit is connected to the first electrode and the second electrode. The read-out circuit provides a first data voltage based on a first charge amount provided from the first electrode to a first data line, and provides a second data voltage based on a second charge amount provided from the second electrode to the first data line.
