摘要： A pixel cell includes a substrate, an epitaxial layer, and a photo converting device in the epitaxial layer. The epitaxial layer has a doping concentration profile of embossing shape, and includes a plurality of layers that are stacked on the substrate. The photo converting device does not include a neutral region that has a constant potential in the vertical direction. Therefore, the image sensor including the pixel cell has high quantization efficiency, and a crosstalk between photo-converting devices is decreased.
