Abstract

An image sensor may include an array of pixels having a color filter layer. The color filter layer may include colored elements and clear elements. The clear elements may be formed from transparent dielectric material. The color filter layer may include a grid of light-blocking material that forms color filter container structures having an array of openings in which the colored elements and the clear elements are formed. The color filter container structures may be formed from the same transparent dielectric material that forms the clear elements. The color filter container structures may be formed from opaque materials or transparent materials that form structures such as planarization layers, microlenses, or antireflection coatings for the array of pixels. The material used to form the color filter container structures may have a refractive index that is sufficiently high to prevent light from passing between adjacent elements in the color filter layer.
