Abstract
An image pickup device includes pixels, each including a photoelectric conversion unit and a transfer unit. The photoelectric conversion unit includes a first-conductivity-type first semiconductor region and a second-conductivity-type second semiconductor region. A second-conductivity-type third semiconductor region is formed on at least a part of a gap between a photoelectric conversion unit of a first pixel and a photoelectric conversion unit of a second pixel adjacent to the first pixel. A first-conductivity-type fourth semiconductor region having an impurity concentration higher than an impurity concentration of the first semiconductor region is formed between the photoelectric conversion unit and the third semiconductor region. A first-conductivity-type fifth semiconductor region having an impurity concentration higher than the first semiconductor region is arranged between the photoelectric conversion unit and the third semiconductor region and is arranged deeper than fourth semiconductor region.
