Abstract:
The present disclosure is directed to a method for forming a light blocking material layer on a back side illuminated image sensor device. The light blocking material layer can block or absorb light rays incoming to the back side illuminated image sensor device at grazing incident angles. The light blocking material layer can be formed using a self-aligned process that does not require the use of a photolithography mask or photolithography operations. For example, the light blocking material layer can be formed over an image sensor device and subsequently etched so that the light blocking material layer remains in areas where light rays incoming at grazing incident angles enter the back side illuminated image sensor device.

Claim (Index 14):
The semiconductor image sensor of  claim 9 , wherein the light blocking layer comprises an infrared color filter material.
