Abstract
An imaging device includes a semiconductor substrate, a photoelectric converter that converts incident light into a charge, a first impurity region located in the semiconductor substrate, where the first impurity region accumulates the charge and contains impurities of a first conductivity type, a second impurity region located in the semiconductor substrate, where the second impurity region contains impurities of the first conductivity type and is different from the first impurity region, a third impurity region located in the semiconductor substrate, between the first impurity region and the second impurity region in plan view, where the third impurity region contains impurities of a second conductivity type that differs from the first conductivity type, and a first contact located on the semiconductor substrate and electrically connected to the third impurity region. The first contact includes a semiconductor containing impurities of the second conductivity type.
