Abstract:
An image sensor pixel includes a photo-sensor region, a microlens, a first color filter layer, and a second color filter layer. The photo-sensor region is disposed within a semiconductor die. The microlens is disposed on the semiconductor die in optical alignment with the photo-sensor region. The first color filter layer is disposed between the photo-sensor region and the microlens. The second color filter layer is disposed on an opposite side of the microlens as the first color filter layer.
