  • BACKSIDE ILLUMINATED CMOS IMAGE SENSOR
    Publication number: 20140048898
    Abstract: A backside illuminated (BSI) CMOS image sensor is disclosed. The BSI CMOS image sensor includes: a substrate having a front side and a back side, the substrate including a photodiode formed therein, the photodiode being proximate the back side of the substrate; a metal shielding layer covering the back side of the substrate, the metal shielding layer including an opening formed therein, the opening being arranged in correspondence with the photodiode; and a light-absorbing layer formed on each side face of the opening. The light-absorbing layer coated on the side faces of the opening prevents the occurrence of photon cross-talk and hence improves imaging quality of the BSI CMOS image sensor.
