Patent attributes
A solid-state image sensor comprising pixels, each including a first region of a first conductivity type, a second region of the first conductivity type formed in a position shifted from the first region in a first direction, a third region of a second conductivity type formed between the first and second regions, a fourth region of the first conductivity type formed in a position shifted from the third region in a second direction, a first gate electrode of a transistor arranged between the first and fourth regions, a second gate electrode of a transistor arranged between the second and fourth regions, and a fifth region of the second conductivity type formed between the first and second gate electrodes and between the third and fourth regions, and a concentration of the fifth region is higher than that of the third region.
