Abstract: An image sensor includes: a first substrate including: a first side, a second side, a pixel array region, and an edge region; and a micro lens array on the second side, which includes micro lenses. Each of the micro lenses includes a first lens layer and a second lens layer on the first lens layer. A second mean curvature radius of the second lens layer is smaller than a first mean curvature radius of the first lens layer. A first eccentric degree of the second lens layer on an edge of the pixel array region is greater than a second eccentric degree of the second lens layer at a center of the pixel array region.

Abstract: An image sensor includes a first substrate having a first side and a second side opposite each other, and including a pixel array region having plurality of active regions disposed at the first side, a shallow trench isolation structure disposed at the first side of the first substrate and isolating each of the plurality of active regions, a plurality of floating diffusion regions disposed at the plurality of active regions of the first substrate, and a floating diffusion region connector connecting the plurality of floating diffusion regions with each other. The floating diffusion region connector is buried in the shallow trench isolation structure and an upper surface of the floating diffusion region connector is lower than an upper surface of the shallow trench isolation structure.

Abstract: An image sensor includes a substrate and a pixel separation portion disposed in the substrate and separating first pixels and second pixels from each other. The first pixels and the second pixels are alternately arranged in a first direction and a second direction which intersect each other. Each of the first pixels has a first width in the first direction. Each of the second pixels has a second width in the first direction, which is narrower than the first width. The pixel separation portion includes a main separation portion between the first and second pixels, and protrusions, each of which protrudes from a side surface of the main separation portion in at least one of the first and second directions. Ones of the protrusions protrude into a respective one of the first pixels to divide the respective one of the first pixels into a plurality of sub-pixels.
