Abstract
The present disclosure provides an image sensor including a unit. The unit includes a phase detection auto focus (PDAF) pixel, sensing pixels, and a light-shielding grid. The PDAF pixel is on a substrate, in which the PDAF pixel includes four photodiodes and a first color filter layer on the four photodiodes. The sensing pixels are on the substrate and surround the PDAF pixel, in which each of the sensing pixels includes a single photodiode and a second color filter layer on the single photodiode. The light-shielding grid surrounds the first color filter layer, in which the light-shielding grid includes a first portion and a second portion from a top view, the first portion is closer to a center of the substrate than the second portion, and a width of the first portion is larger than a width of the second portion.
