    摘要: A backside illuminated CMOS image sensor comprises a photo active region formed over a substrate using a front side ion implantation process and an extended photo active region formed adjacent to the photo active region, wherein the extended photo active region is formed by using a backside ion implantation process. The backside illuminated CMOS image sensor may further comprise a laser annealed layer on the backside of the substrate. The extended photo active region helps to increase the number of photons converted into electrons so as to improve quantum efficiency.

    摘要: A device includes a semiconductor substrate, which has a front side and a backside. A photo-sensitive device is disposed on the front side of the semiconductor substrate. A first and a second grid line are parallel to each other, and are disposed on the backside of, and overlying, the semiconductor substrate. A stacked layer includes an adhesion layer, a metal layer over the adhesion layer, and a high-refractive index layer over the metal layer. The adhesion layer, the metal layer, and the high-refractive index layer are substantially conformal, and extend on top surfaces and sidewalls of the first and the second grid lines.
