Abstract: Image sensors and fabrication methods thereof. For example, the image sensor may include a first substrate having a first surface and a second surface that are opposite to each other, a plurality of pixels provided in the first substrate and arranged in pixel groups, each pixel group including four pixels arranged in two columns and two rows, a pixel separation structure in the first substrate and including a pixel group separation part that separates each pixel group from adjacent pixel groups and a pixel separation part that separates the pixels in each pixel group from each other, and a plurality of microlenses on the first surface and respectively overlapping the plurality of pixel groups. Each of the microlenses includes a central part that has a first curvature and an edge part that has a second curvature. The first curvature is less than the second curvature.

Abstract: An image sensor includes a first substrate including a focus pixel region and pixel regions around the focus pixel region, each of the focus pixel region and the pixel regions including at least one photoelectric conversion region, color filters provided on the focus pixel region and the pixel regions, respectively, and on a first surface of the first substrate, and micro lenses provided on the color filters, respectively. The micro lenses include an auto-focus lens on the focus pixel region, a first micro lens adjacent to the auto-focus lens, and a standard micro lens spaced apart from the auto-focus lens.
