Abstract
An imaging device includes a pixel region including an amplifying transistor that includes a first gate and that outputs a signal voltage corresponding to an amount of signal charge, a first peripheral region including at least one first peripheral transistor including a second gate, the first peripheral region being located outside the pixel region, and a semiconductor substrate provided with the amplifying transistor and the at least one first peripheral transistor. A gate length of the second gate is shorter than a gate length of the first gate. When at least one type of impurity that contributes to suppression of transient enhanced diffusion of a conductive impurity is defined as a first specific species, the at least one first peripheral transistor includes a first specific layer located in the semiconductor substrate, the first specific layer containing a conductive impurity and the first specific species.
