  • Publication number: 20250063834
    Abstract: A polysilicon well is formed at a cross-road portion between a plurality of pixel sensors in a pixel sensor array. Moreover, the underlying oxide layer between the polysilicon well and a semiconductor layer of the pixel sensor array may be thinner than other areas of the oxide layer. The polysilicon well and the thinner oxide layer may reduce the likelihood of and/or the magnitude of lateral etching that occurs during etching of the semiconductor layer to form recesses in which a BDTI structure of the pixel sensor array is formed. Moreover, the bottom of the BDTI structure being surrounded by the polysilicon well enables a voltage bias to be applied to the BDTI structure through the polysilicon well to passivate damage that might have occurred to the semiconductor layer around the bottom of the BDTI structure.

  • Patent number: 12124989
    Abstract: Systems and methods are disclosed for determining a visual indicator for a package based on a delivery address for the package and a location of the delivery address along a delivery route. An optimized delivery route may be created for packages to be delivered at a given time. At the fulfillment center, a delivery system may label a package prior to loading the package on a delivery vehicle. The delivery system may determine the appropriate visual indicator (e.g., color and/or pattern) or the visual indicator may be randomly selected. The delivery system may generate a label having the visual indicator. The package may be deposited into a certain bin with other packages having a delivery address in close proximity. The delivery system may generate a user interface on a user device that indicates that the package has a certain visual indicator to facilitate sorting and identification of the package.
