  • Publication number: 20240079268
    Abstract: The present disclosure, in some embodiments, relates to a method of forming an integrated chip structure. The method may be performed by forming a plurality of interconnect layers within a first interconnect structure disposed over an upper surface of a first semiconductor substrate. An edge trimming process is performed to remove parts of the first interconnect structure and the first semiconductor substrate along a perimeter of the first semiconductor substrate. The edge trimming process results in the first semiconductor substrate having a recessed surface coupled to the upper surface by way of an interior sidewall disposed directly over the first semiconductor substrate. A dielectric capping structure is formed onto a sidewall of the first interconnect structure after performing the edge trimming process.

  • Publication number: 20230402488
    Abstract: A pixel sensor may include a vertically arranged (or vertically stacked) photodiode region and floating diffusion region. The vertical arrangement permits the photodiode region to occupy a larger area of a pixel sensor of a given size relative to a horizontal arrangement, which increases the area in which the photodiode region can collect photons. This increases performance of the pixel sensor and permits the overall size of the pixel sensor to be reduced. Moreover, the transfer gate may surround at least a portion of the floating diffusion region and the photodiode region, which provides a larger gate switching area relative to a horizontal arrangement. The increased gate switching area may provide greater control over the transfer of the photocurrent and/or may reduce switching delay for the pixel sensor.

  • Publication number: 20230387171
    Abstract: A pixel sensor may include a deep trench isolation (DTI) structure that extends the full height of a substrate in which a photodiode of the pixel sensor is included. Incident light entering the pixel sensor at a non-orthogonal angle is absorbed or reflected by the DTI structure along the full height of the substrate. In this way, the DTI structure may reduce, minimize, and/or prevent the incident light from traveling through the pixel sensor and into an adjacent pixel sensor along the full height of the substrate. This may increase the spatial resolution of an image sensor in which the DTI structure is included, may increase the overall sensitivity of the image sensor, may reduce and/or prevent color mixing between pixel sensors of the image sensor, and/or may decrease image noise after color correction.

  • Publication number: 20230387152
    Abstract: A pixel sensor includes a transfer fin field effect transistor (finFET) to transfer a photocurrent from a photodiode to a drain region. The transfer finFET includes at least a portion of the photodiode, an extension region associated with the drain region, a plurality of channel fins, and a transfer gate at least partially surrounding the channel fins to control the operation of the transfer finFET. In the transfer finFET, the transfer gate is wrapped around (e.g., at least three sides) of each of the channel fins, which provides a greater surface area over which the transfer gate is enabled to control the transfer of electrons. The greater surface area results in greater control over operation of the finFET, which may reduce switching times of the pixel sensor (which enables faster pixel sensor performance) and may reduce leakage current of the pixel sensor relative to a planar transfer transistor.

  • Publication number: 20230369369
    Abstract: Some implementations described herein provide pixel sensor configurations and methods of forming the same. In some implementations, one or more transistors of a pixel sensor are included on a circuitry die (e.g., an application specific integrated circuit (ASIC) die or another type of circuitry die) of an image sensor device. The one or more transistors may include a source follower transistor, a row select transistor, and/or another transistor that is used to control the operation of the pixel sensor. Including the one or more transistors of the pixel sensor (and other pixel sensors of the image sensor device) on the circuitry die reduces the area occupied by transistors in the pixel sensor on the sensor die. This enables the area for photon collection in the pixel sensor to be increased.

  • Patent number: 11670651
    Abstract: A pixel array includes octagon-shaped pixel sensors and a combination of visible light pixel sensors (e.g., red, green, and blue pixel sensors) and near infrared (NIR) pixel sensors. The color information obtained by the visible light pixel sensors and the luminance obtained by the NIR pixel sensors may be combined to increase the low-light performance of the pixel array, and to allow for low-light color images in low-light applications. The octagon-shaped pixel sensors may be interspersed in the pixel array with square-shaped pixel sensors to increase the utilization of space in the pixel array, and to allow for pixel sensors in the pixel array to be sized differently. The capability to accommodate different sizes of visible light pixel sensors and NIR pixel sensors permits the pixel array to be formed and/or configured to satisfy various performance parameters.

  • Publication number: 20230067395
    Abstract: In some implementations, a pixel array may include a near infrared (NIR) cut filter layer for visible light pixel sensors of the pixel array. The NIR cut filter layer is included in the pixel array to absorb or reflect NIR light for the visible light pixel sensors to reduce the amount of MR light absorbed by the visible light pixel sensors. This increases the accuracy of the color information provided by the visible light pixel sensors, which can be used to produce more accurate images. In some implementations, the visible light pixel sensors and/or MR pixel sensors may include high absorption regions to adjust the orientation of the angle of refraction for the visible light pixel sensors and/or the MR pixel sensors, which may increase the quantum efficiency of the visible light pixel sensors and/or the MR pixel sensors.
