  • Publication number: 20240234460
    Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.

  • Patent number: 11990488
    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.

  • Patent number: 11985438
    Abstract: A pixel array includes a plurality of dark pixel sensors configured to generate dark current calibration information for a plurality of visible light pixel sensors included in the pixel array. The plurality of dark pixel sensors may generate respective dark current measurements for each of the plurality of visible light pixel sensors or for small subsets of the plurality of visible light pixel sensors. In this way, each of the plurality of visible light pixel sensors may be individually calibrated (or small subsets of the plurality of visible light pixel sensors may be individually calibrated) based on an estimated dark current experienced by each of the plurality of visible light pixel sensors. This may enable more accurate dark current calibration of the visible light pixel sensors included in the pixel array, and may be used to account for large differences in estimated dark currents for the visible light pixel sensors.

    Abstract: A CMOS image sensor includes PDAF pixels distributed in an array of image pixels in plan view. Each PDAF pixel includes m×m binned photodiodes, a PDAF color filter overlying the binned photodiodes and laterally surrounded by a first isolation structure, and a PDAF micro-lens overlying the PDAF color filter. A first horizontal distance between a center of the PDAF color filter and a center of the binned photodiodes varies depending on a location of the PDAF pixel in plan view in the CMOS image sensor. Additionally, the first isolation structure includes a first low-n dielectric grid, a second low-n dielectric grid underlying the first low-n dielectric grid, and a metal grid enclosed by the second low-n dielectric grid. The second low-n dielectric grid includes a filler dielectric material different from a second low-n dielectric grid material.
