Patent ID: 7671438

Claim:
A solid-state imaging device, comprising: a plurality of first pixels and a plurality of second pixels which are formed in a semiconductor substrate, wherein each of the first pixels includes a first impurity region of a first conductivity type formed in the semiconductor substrate, a second impurity region of a second conductivity type formed on the first impurity region and serving as a first photodiode, and a fifth impurity region of a first conductivity type formed on a surface side of the semiconductor substrate on the second impurity region, and each of the second pixels includes a third impurity region of a first conductivity type formed in the semiconductor substrate, a fourth impurity region of a second conductivity type formed on the third impurity region and serving as a second photodiode, and an impurity region of a first conductivity type having a same impurity concentration as the first impurity region and formed on a surface side of the semiconductor substrate on the fourth impurity region or a sixth impurity region of a first conductivity type having a lower impurity concentration than the fifth impurity region and formed on a surface side of the semiconductor substrate on the fourth impurity region.
