Abstract: An image sensor may include a first substrate having first and second surfaces and including unit pixel regions, each of which includes a device isolation pattern and a photoelectric conversion region adjacent to the first surface of the first substrate, a pixel isolation pattern provided in the first substrate to define the unit pixel regions and to penetrate the device isolation pattern, a first impurity region and a floating diffusion region provided in the first substrate and adjacent to the first surface, a second substrate provided on the first substrate to have third and fourth surfaces, a second impurity region provided in the second substrate and adjacent to the third surface, and ground and body contacts coupled to the first and second impurity regions, respectively. The ground contact and the body contact may be electrically separated from each other.
