Summary:To provide an image sensor structure.SOLUTION: The image sensor structure includes a substrate. The substrate includes a first side and a second side which is a side opposite to the first side. A photodetector extends to the first side of the substrate. A separation structure includes a first separation segment and a second separation segment which extend through the substrate. Each of the first separation segment and the second separation segment is located opposite to the photodetector and includes a dielectric. A first metal line is located on the first side of the substrate. A dummy contact structure includes a first dummy segment and a second dummy segment. Both of the first dummy segment and the second dummy segment include a metal and extend from the first metal line to the first separation segment and the second separation segment.SELECTED DRAWING: Figure 1 【課題】いくつかの実施形態では、本開示は、画像センサー構造に関する。【解決手段】該画像センサー構造は、基板を含む。該基板は、第1の側と、該第1の側の反対側である第2の側とを含む。光検出器は、該基板の該第1の側に延在する。分離構造は、該基板を通って延在する第1の分離セグメント及び第2の分離セグメントを含む。該第1の分離セグメントと該第2の分離セグメントとは、それぞれ該光検出器の反対側にあり、誘電体を含む。第1の金属線は、該基板の該第1の側にある。ダミー接点構造は、第1のダミーセグメントと、第2のダミーセグメントとを含む。該第1のダミーセグメントと該第2のダミーセグメントとは、いずれも金属を含み、それぞれ該第1の金属線から該第1の分離セグメントと該第2の分離セグメントとまで延在する。【選択図】図1
