Abstract
A solid-state image capturing apparatus, comprising a semiconductor substrate including a first region of a first conductivity type, charge accumulation regions of a second conductivity type, transistors each outputting a signal based on charges accumulated in the charge accumulation region, a second region of the first conductivity type formed in a position deeper than the charge accumulation regions and shallower than the first region so as to be electrically conducted to the first region, whose impurity concentration is higher than that of the first region, and a third region of the second conductivity type formed between the second region and the first region, wherein the second region is formed across a region including two or more transistors in a planar view and supplies a current to each of the two or more transistors.
