  • Dark current mitigation with diffusion control
    Patent number: 10090426
    Abstract: A photosensor device for reducing dark current is disclosed. The photosensor device includes a photon absorbing layer and two or more photosensor diffusions in said absorbing layer. The photosensor diffusions in the absorbing layer have edges of their diffusions separated in said absorbing layer by less than two minority carrier diffusion lengths. The photosensor device also includes in one embodiment one or more diffusion control junction diffusions in the absorbing layer and in proximity to the photosensor diffusions. In another embodiment the photosensor diffusions are selectively biased to operate as photosensor diodes or as diffusion impediments.
