Abstract
A CMOS imager includes a photosite array and a microlens array. The microlens array comprises microlenses of a first type and microlenses of a second type, the microlenses of first type being manufactured according to a first circular template having a first radius, the microlenses of second type being manufactured according to a second circular template having a second radius inferior to the first radius, and the first and second templates having overlap areas. One advantage is that the CMOS imager has a high fill rate.
