  • CMOS image sensor with epitaxial passivation layer
    Patent number: 9349768
    Abstract: The present disclosure provides a complimentary metal-oxide-semiconductor (CMOS) image sensor (CIS) device. In accordance with some embodiments, the device includes a semiconductor region having a front surface and a back surface; a light-sensing region extending from the front surface towards the back surface within the semiconductor region; a gate stack formed over the semiconductor region; and at least one epitaxial passivation layer disposed at least one of over and below the light-sensing region. In some embodiments, the at least one epitaxial passivation layer includes a p-type doped silicon (Si) layer.
    Type: Grant
