Abstract

Pixel arrays are provided for image sensors that have barriers between color filters in an array of color filters. Color filter barriers may be formed from a transparent or semi-transparent material. Color filter barriers may be formed from a low refractive index material. Color filters may be etched and color filter barrier material may be formed in the etched regions of the color filters. If desired, a layer of color filter barrier material may be etched to form open regions and color filter material may be formed in the open regions of the color filter barrier material. An image sensor may be a front-side illuminated image sensor or a back-side illuminated image sensor.
