Patent ID: 8710559

Claim:
A back-illuminated solid-state imaging apparatus comprising: a transfer gate electrode formed on a semiconductor substrate; and a photoelectric conversion unit including an electric charge storage area that is formed from a surface side of the semiconductor substrate in a depth direction, the electric charge storage area being formed of a first conductive type impurity area that is formed so as to partially overlap the transfer gate electrode, a transfer auxiliary area formed of a second conductive type impurity area that is formed in such a manner as to partially overlap the transfer gate electrode, the transfer auxiliary area being formed in an upper layer of the electric charge storage area, and a dark current suppression area that is a first dark current suppression area formed in an upper layer of the transfer auxiliary area and formed so as to have positional alignment in such a manner that an end portion of the first dark current suppression area on a side overlapping the transfer gate electrode is at the same position as an end portion of the transfer auxiliary area partially overlapping the transfer gate electrode, the dark current suppression area being formed of an impurity area having a same conductive type as the transfer auxiliary area and wherein the impurity area has the same conductive type in a higher concentration than that of the transfer auxiliary area.
