  • Publication number: 20240021635
    Abstract: A grid structure in a pixel array may be at least partially angled or tapered toward a top surface of the grid structure such that the width of the grid structure approaches a near-zero width near the top surface of the grid structure. This permits the spacing between color filter regions in between the grid structure to approach a near-zero spacing near the top surfaces of the color filter regions. The tight spacing of color filter regions provided by the angled or tapered grid structure provides a greater surface area and volume for incident light collection in the color filter regions. Moreover, the width of the grid structure may increase at least partially toward a bottom surface of the grid structure such that the wider dimension of the grid structure near the bottom surface of the grid structure provides optical crosstalk protection for the pixel sensors in the pixel array.
