    摘要： An image sensor is provided. The image sensor includes a substrate and an isolation structure disposed over the substrate. The isolation structure has isolation segments in a cross-sectional view and is electrically non-conductive, and the isolation segments form concave tanks that define pixel regions. The image sensor also includes bottom electrodes disposed at bottoms of the concave tanks and reflective layers disposed on sidewalls of the concave tanks. The image sensor further includes a photoelectric conversion layer disposed on the isolation structure and in the concave tanks and a top electrode disposed on the photoelectric conversion layer. Moreover, the image sensor includes an encapsulation layer disposed on the top electrode.
