To minimize optical and electrical and crosstalk, the array of pixels may include deep trench isolation structures interposed between adjacent pairs of photodiodes. In order to maximize quantum efficiency, the array of pixels may include a reflective stack formed under the photodiodes and the deep trench isolation structures. The deep trench isolation structures may be formed from doped glass, doped polysilicon, or metal having a doped oxide liner. The reflective stack may include multiple layers of materials having different indices of refraction. The reflective stack may include oxide, nitride, and semiconductor layers. The deep trench isolation structures may extend from the top of the photodiodes down to the reflective stack. The deep trench isolation structures may have a 50 to 1 aspect ratio."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High efficiency image sensor pixels with deep trench isolation structures and embedded reflectors","description":"An image sensor with an array of pixels is provided.
