IMAGE SENSOR AND ELECTRONIC APPARATUS INCLUDING THE IMAGE SENSOR

Abstract: an image sensor includes a sensor substrate including a plurality of pixels sensing incident light, a nano-optical micro-lens array including a plurality of nano-optical micro-lenses respectively corresponding to the plurality of pixels, and a color filter array disposed between the sensor substrate and the nano-optical micro-lens array and including a plurality of color filters. each of the plurality of nano-optical micro-lenses includes a plurality of nanostructures to condense the incident light onto a corresponding pixel, and when viewed in a cross-section of the nano-optical micro-lens array, a fill factor denotes a ratio of an area of the nanostructures arranged within a reference circle among the plurality of nanostructures included in one of the plurality of nano-optical micro-lenses, and the reference has a pixel size corresponding to the one nano-optical micro-lens as a diameter, the fill factor is greater than or equal to 95%.
