Abstract
According to one embodiment, a solid-state imaging device includes a photodiode includes an N-type region and a P-type region, a floating diffusion region, and a transfer transistor. The N-type diffusion region of the photodiode comprises a first semiconductor region and a second semiconductor region formed shallower than the first semiconductor region. An end portion of the first semiconductor region is positioned on the floating diffusion region side rather than an end portion of a gate electrode of the transfer transistor. An end portion of the second semiconductor region is set in substantially the same position as that of the end portion of the gate electrode of the transfer transistor.
