    Abstract: Among other things, one or more support structures for integrated circuitry and techniques for forming such support structures are provided. A support structure comprises one or more trench structures, such as a first trench structure and a second trench structure formed around a periphery of integrated circuitry. In some embodiments, one or more trench structures are formed according to partial substrate etching, such that respective trench structures are formed into a region of a substrate. In some embodiments, one or more trench structures are formed according to discontinued substrate etching, such that respective trench structures comprise one or more trench portions separated by separation regions of the substrate. The support structure mitigates stress energy from reaching the integrated circuitry, and facilitates process-induced charge release from the integrated circuitry.

    Abstract: An embodiment image sensor includes a pixel region spaced apart from a black level control (BLC) region by a buffer region. In an embodiment, a light shield is disposed over the BLC region and extends into the buffer region. In an embodiment, the buffer region includes an array of dummy pixels. Such embodiments effectively reduce light cross talk at the edge of the BLC region, which permits more accurate black level calibration. Thus, the image sensor is capable of producing higher quality images.

    Abstract: A method of creating a reflective shield for an image sensor device includes depositing a first dielectric layer on a substrate, wherein a photodiode is on the substrate. The method further includes removing surface topography by performing chemical mechanical polishing (CMP) on the first dielectric layer. The method further includes patterning the substrate to define an area on a surface of the first dielectric layer, wherein the area is directly above the photodiode. The method further includes depositing a layer of a material with high reflectivity on the substrate, wherein the material fills the area on the surface of the first dielectric layer. The method further includes removing excess material with high reflectivity, wherein the reflective shield is formed and is embedded in the first dielectric layer. The method further includes depositing a second dielectric material on the substrate, wherein the second dielectric material covers the reflective shield.
