A pixel array of an image sensor includes a plurality of pixel groups. Each pixel group includes a plurality of unit pixels adjacent to each other and respectively including photoelectric conversion elements disposed in a semiconductor substrate, a color filter shared by the plurality of unit pixels, and a plurality of microlenses disposed on the color filter and having sizes different from each other such that the plurality of microlenses respectively focus an incident light to the photoelectric conversion elements included in the plurality of unit pixels. Deviations of sensing sensitivity of unit pixels are reduced and quality of images captured by the image sensor is enhanced by adjusting sizes of microlenses.

Pixel array of image sensor and method of manufacturing the same

An image sensor includes a device isolation layer disposed in a substrate and defining pixel regions, and a grid pattern on a surface of the substrate. The grid pattern overlaps the device isolation layer between adjacent pixel regions in a direction perpendicular to the surface. The grid pattern has a width less than a width of the device isolation layer.

Image sensors

An image sensor includes a photoelectric conversion layer including a plurality of first photoelectric conversion elements and a plurality of second photoelectric conversion elements adjacent to the first photoelectric conversion elements. A light shield layer shields the second photoelectric conversion elements and has respective openings therein that provide light transmission to respective ones of the first photoelectric conversion elements. The image sensor further includes an array of micro-lenses on the photoelectric conversion layer, each of the micro-lenses overlapping at least one of the first photoelectric conversion elements and at least one of the second photoelectric conversion elements.
