    摘要: A pixel structure includes a substrate body having a light entrance surface, a plurality of first photodiodes formed in the substrate body at a first depth with respect to the light entrance surface, and a second photodiode formed in the substrate body at a second depth with respect to the light entrance surface. The first depth corresponds to a photon absorption length in a material of the substrate body at a first wavelength range, and the second depth corresponds to a photon absorption length in the material of the substrate body at a second wavelength range that is different from the first wavelength range.
