    摘要: A method and apparatus for a low resistance image sensor contact, the apparatus comprising a photosensor disposed in a substrate, a first ground well disposed in a first region of the substrate, the first ground well having a resistance lower than the substrate, and a ground line disposed in a region adjacent to the first ground well. The first ground well is configured to provide a low resistance path to the ground line from the substrate for excess free carriers in the first region of the substrate. The apparatus may optionally comprise a second ground well having a lower resistance than the first ground well and disposed between the first ground well and the ground line, and may further optionally comprise a third ground well having a lower resistance than the second ground well and disposed between the second ground well and the ground line.

    摘要: A method includes forming a first implantation mask comprising a first opening, implanting a first portion of a semiconductor substrate through the first opening to form a first doped region, forming a second implantation mask comprising a second opening, and implanting a second portion of the semiconductor substrate to form a second doped region. The first portion of the semiconductor substrate is encircled by the second portion of the semiconductor substrate. A surface layer of the semiconductor substrate is implanted to form a third doped region of an opposite conductivity type than the first and the second doped regions. The third doped region forms a diode with the first and the second doped regions.

    摘要: Provided is an image sensor device. The image sensor device includes a substrate having a front side and a back side. The image sensor includes first and second radiation-detection devices that are disposed in the substrate. The first and second radiation-detection devices are operable to detect radiation waves that enter the substrate through the back side. The image sensor also includes an anti-reflective coating (ARC) layer. The ARC layer is disposed over the back side of the substrate. The ARC layer has first and second ridges that are disposed over the first and second radiation-detection devices, respectively. The first and second ridges each have a first refractive index value. The first and second ridges are separated by a substance having a second refractive index value that is less than the first refractive index value.
