  • Patent number: 10942304
    Abstract: The present technology relates to a solid-state imaging element, a manufacturing method of the same, and an electronic device that achieve the extension of a dynamic range by making a difference in light-receiving sensitivity between low-sensitivity pixels and high-sensitivity pixels without changing spectral characteristics. The solid-state imaging element includes a pixel array portion in which two kinds of pixels different in light-receiving sensitivity, high-sensitivity pixels and low-sensitivity pixels are arrayed. The low-sensitivity pixels have a gray filter on or under a color filter to decrease light transmission factor in a visible-light region by a predetermined ratio.

The method randomly selects one primary link for use, responsive to identifying more than one primary link that is non-defective. The method identifies any secondary links useable to decrease the path distance and orthogonal to a primary link, responsive to the primary links being defective. The method randomly selects one secondary link for use, responsive to identifying more than one secondary link that is non-defective. The method identifies any tertiary links useable to decrease the path distance and reverse in direction to a primary link, responsive to the secondary links being defective.
