    摘要: An image sensor device including a semiconductor substrate that includes an array region and a black level correction region. The array region contains a plurality of radiation-sensitive pixels. The black level correction region contains one or more reference pixels. The substrate has a front side and a back side. The image sensor device includes a first compressively-stressed layer formed on the back side of the substrate. The first compressively-stressed layer contains silicon oxide, and is negatively charged. The second compressively-stressed layer contains silicon nitride, and is negatively charged. A metal shield is formed over at least a portion of the black level correction region. The image sensor device includes a third compressively-stressed layer formed on the metal shield and the second compressively-stressed layer. The third compressively-stressed layer contains silicon oxide. A sidewall of the metal shield is protected by the third compressively-stressed layer.

    摘要: A method includes performing a grinding to a backside of a semiconductor substrate, wherein a remaining portion of the semiconductor substrate has a back surface. A treatment is then performed on the back surface using a method selected from the group consisting essentially of a dry treatment and a plasma treatment. Process gases that are used in the treatment include oxygen (O2). The plasma treatment is performed without vertical bias in a direction perpendicular to the back surface.

    摘要: The present disclosure relates to a method and composition to limit crystalline defects introduced in a semiconductor device during ion implantation. A high-temperature low dosage implant is performed utilizing a tri-layer photoresist which maintains the crystalline structure of the semiconductor device while limiting defect formation within the semiconductor device. The tri-layer photoresist comprises a layer of spin-on carbon deposited onto a substrate, a layer of silicon containing hard-mask formed above the layer of spin-on carbon, and a layer of photoresist formed above the layer of silicon containing hard-mask. A pattern formed in the layer of photoresist is sequentially transferred to the silicon containing hard-mask, then to the spin-on carbon, and defines an area of the substrate to be selectively implanted with ions.
