  • Pixel cell, image sensor, and manufacturing method
    Patent number: 9847361
    Abstract: A pixel cell, a method for manufacturing the same and an image sensor including the same are provided. The pixel cell includes: a substrate; a photodiode, a pass transistor and a floating diffusion structure respectively formed on the substrate, in which the pass transistor is formed between the photodiode and the floating diffusion structure; and a PINNED structure, formed on the substrate and connected with the floating diffusion structure, in which a reset voltage of the floating diffusion structure is higher than a depletion voltage of the PINNED structure.
    Type: Grant
