Abstract
Image sensors for Phase-Detection Auto Focus (PDAF) are provided. An image sensor includes a pixel including a plurality of photodiodes disposed in a semiconductor material according to an arrangement. The arrangement defines a first image subpixel comprising a plurality of first photodiodes, a second image subpixel comprising a plurality of second photodiodes, and a third image subpixel including a plurality of third photodiodes, and a phase detection subpixel comprising a first photodiode, a second photodiode, or a third photodiodes. The pixel can include a plurality of first micro-lenses disposed individually overlying at least a subset of the plurality of photodiodes of the first, second and third image subpixels. The pixel can also include a second micro-lens disposed overlying the phase detection subpixel, a first micro-lens of the first micro-lenses having a first radius less than a second radius of the second micro-lens.
