Abstract
An image sensor device is disclosed, which blocks noise of a pad area. The image sensor device includes a substrate, a pad, and an impurity area. The substrate includes a first surface and a second surface, and includes first conductive impurities. The pad is disposed at the first surface of the substrate. The impurity area is formed in the substrate to overlap with the pad in a first direction, the impurity area being includes second conductive impurities different from the first conductive impurities.
