  • Patent number: 11869906
    Abstract: A pixel cell with an elevated floating diffusion region is formed to reduce diffusion leakage (e.g., gate induced drain leakage, junction leakage, etc.). The floating diffusion region can be elevated by separating a doped floating diffusion region from the semiconductor substrate by disposing an intervening layer (e.g., undoped, lightly doped, etc.) on the semiconductor substrate and beneath the doped floating diffusion region. For instance, the elevated floating diffusion region can be formed by stacked material layers composed of a lightly or undoped base or intervening layer and a heavy doped (e.g., As doped) “elevated” layer. In some examples, the stacked material layers can be formed by first and second epitaxial growth layers.
