Abstract
An image sensor has an array of image sensor pixels. Each image sensor pixel may have a gradient index lens formed in a passivation layer. The gradient index lens may be a converging or diverging gradient index lens. The gradient index lens may have a gradient index profile that is smooth or a gradient index profile having distinct regions of lower or higher refractive index. Regions of lower refractive index may be formed from ion implantation in the passivation layer. Each pixel may also have a polymer microlens, a color filter, a dielectric stack, and a photosensitive element in a substrate.
