Patent abstract
A solid-state imaging device includes a first and second pixel regions. In the first pixel region, a photoelectric conversion unit, a floating diffusion region (FD), and a transferring transistor are provided. In the second pixel region, an amplifying transistor, and a resetting transistor are provided. A first element isolation portion is provided in the first pixel region, while a second element isolation portion is provided in the second pixel region. An amount of protrusion of an insulating film into a semiconductor substrate in the first element isolation portion is smaller, than that in the second element isolation portion.
