Abstract
A solid-state imaging device includes: pixels arranged in a matrix, a semiconductor substrate; a first electrode formed above the semiconductor substrate for each of the pixels; a photoelectric conversion film formed on the first electrode, for photoelectric conversion of light into signal charge; a charge accumulation region formed in the semiconductor substrate for accumulating the signal charge generated through the photoelectric conversion in the photoelectric conversion film; a contact plug for electrically connecting the first electrode and the charge accumulation region in a corresponding pixel; a high-concentration impurity region formed on a surface of the charge accumulation region, in a region in contact with the contact plug; a surface impurity region formed on the surface of the charge accumulation region, in a region not in contact with the contact plug; and a low-concentration impurity region formed between the high-concentration impurity region and the surface impurity region.
