Himax Imaging Works on Small Pixel BSI Designs

According to the patent application US20110169055, Himax Imaging works on BSI pixel design. The company proposes non-self-aligned transfer gate on top of pinning layer to achieve low image lag and dark current. Also, the application says that "BSI red response may be boosted by forming reflection layers by the extended transfer gate poly on top of PD".

    Why is the dark current lower in this case?

    Because the PD edge part is better protected deep under the transfer gate.
