Abstract
Provided is a back-illuminated solid-state image pickup apparatus having an improved color separation characteristic. A photo detector includes a first photo detector unit and a second photo detector unit disposed deeper than the first photo detector unit with respect to a back surface of a semiconductor substrate, wherein the first photo detector unit includes a first-conductivity-type first semiconductor region where carriers generated through photo-electric conversion are collected as signal carriers. A readout portion includes a first-conductivity-type second semiconductor region extending in a depth direction such that the carriers collected in the first semiconductor region are read out to a front surface of the semiconductor substrate. A unit that reduces the amount of light incident on the second semiconductor region is provided.
