Original Abstract Submitted

An imaging device includes a pixel region and a first peripheral region. The pixel region includes a pixel substrate portion and an amplifying transistor that outputs a signal voltage corresponding to an amount of signal charge. The amplifying transistor is located in the pixel substrate portion. The first peripheral region includes a first peripheral substrate portion and a first peripheral transistor. The first peripheral transistor is located in the first peripheral substrate portion. The pixel substrate portion and the first peripheral substrate portion are stacked on each other. At least one type of impurity that contributes to inhibition of transient enhanced diffusion of a conductive impurity is defined as a specific species. The first peripheral transistor includes a first specific layer that is located in the first peripheral substrate portion and that contains the conductive impurity and the specific species.
