Abstract
A solid-state imaging device with a structure such that an electrode for reading a signal charge is provided on one side of a light-receiving sensor portion constituting a pixel; a predetermined voltage signal V is applied to a light-shielding film formed to cover an image pickup area except the light-receiving sensor portion; a second-conductivity-type semiconductor area is formed in the center on the surface of a first-conductivity-type semiconductor area constituting a photo-electric conversion area of the light-receiving sensor portion; and areas containing a lower impurity concentration than that of the second-conductivity-type semiconductor area is formed on the surface of the first-conductivity-type semiconductor area at the end on the side of the electrode and at the opposite end on the side of a pixel-separation area.
