摘要:
The invention is to suppress a leak current in a photodiode and an unevenness in the leak currents. In a photoelectric converting device including a channel stop area of a higher concentration than in an element isolating insulation film formed between a photodiode, having an n-type semiconductor area formed in a p-type semiconductor, and an adjacent element, and in a p-type semiconductor layer formed under the element isolating insulation film, and a wiring layer formed in a part on the element isolating insulation film, the wiring layers on the element isolating insulation film adjacent to the photodiodes are unified in an effective area and a potential, and a p-type dark current reducing area of a higher concentration than in the channel stop area is provided in at least a part of an area opposed to the wiring layer across the element isolating insulation film.
