IMAGING DEVICE AND METHOD FOR MANUFACTURING SAME

摘要

An imaging device wherein: a plurality of light-receiving elements 10 are arranged in a two-dimensional matrix shape; each light-receiving element 10 comprises a first electrode 31, a photoelectric conversion layer 20, and a second electrode 32; the photoelectric conversion layer 20 has a laminated structure in which a first compound semiconductor layer 21 having a first type of electrical conductivity, and a second compound semiconductor layer 22 having a second type of electrical conductivity that is the reverse type of electrical conductivity from the first type of electrical conductivity, are laminated from the first electrode side; the second compound semiconductor layer is removed in regions 11 between the light-receiving elements 10; the first electrode 31 and the first compound semiconductor layer 21 are shared among the light-receiving elements; and the impurity concentration of the first compound semiconductor layer 21A in the vicinity of the first electrode is lower than the impurity concentration of the first compound semiconductor layer 21B in the vicinity of the second compound semiconductor layer.
