Abstract:
The present disclosure relates to a semiconductor image sensor with improved quantum efficiency. The semiconductor image sensor can include a semiconductor layer having a first surface and a second surface opposite of the first surface. An interconnect structure is disposed on the first surface of the semiconductor layer, and radiation-sensing regions are formed in the semiconductor layer. The radiation-sensing regions are configured to sense radiation that enters the semiconductor layer from the second surface and groove structures are formed on the second surface of the semiconductor layer.

Claim (Index 11):
A semiconductor image sensor device comprising:\n a semiconductor layer having a front side and a back side opposite of the front side, wherein the back side of the semiconductor layer comprises a plurality of groove structures; a plurality of pixels formed in the semiconductor layer, wherein the plurality of pixels are configured to detect light that enters the semiconductor layer at least through the plurality of groove structures; and a plurality of isolation structures, wherein at least one of the isolation structures is disposed between two pixels of the plurality of pixels and has depth of at least half of a thickness of the semiconductor layer.
