    摘要: An object is to provide a photoelectric conversion element having a side surface with different taper angles by conducting etching of a photoelectric conversion layer step-by-step. A pin photodiode has a high response speed compared with a pn photodiode but has a disadvantage of large dark current. One cause of the dark current is considered to be conduction through an etching residue which is generated in etching and deposited on a side surface of the photoelectric conversion layer. Leakage current of the photoelectric conversion element is reduced by forming a structure in which a side surface has two different tapered shapes, which conventionally has a uniform surface, so that the photoelectric conversion layer has a side surface of a p-layer and a side surface of an n-layer, which are not in the same plane.

    摘要: A photo-sensor having a structure which can suppress electrostatic discharge damage is provided. Conventionally, a transparent electrode has been formed over the entire surface of a light receiving region; however, in the present invention, the transparent electrode is not formed, and a p-type semiconductor layer and an n-type semiconductor layer of a photoelectric conversion layer are used as an electrode. Therefore, in the photo-sensor according to the present invention, resistance is increased an electrostatic discharge damage can be suppressed. In addition, positions of the p-type semiconductor layer and the n-type semiconductor layer, which serve as an electrode, are kept away; and thus, resistance is increased and withstand voltage can be improved.
