Abstract
An image sensor may include a first substrate having first and second surfaces opposite to each other and including a floating diffusion region provided near the first surface, a second substrate provided on the first surface of the first substrate, an intermediate substrate disposed between the first and second substrates, a first transistor disposed on a bottom surface of the intermediate substrate, a contact pattern electrically connecting the first transistor to the floating diffusion region, an upper interconnection layer provided on a bottom surface of the intermediate substrate, a lower interconnection layer between the upper interconnection layer and the second substrate, conductive pads electrically connecting the upper and lower interconnection layers, and a capacitor disposed on the second substrate. The contact pattern may penetrate the intermediate substrate and may be in contact with the floating diffusion region. The capacitor may be closer to the second substrate than the conductive pads.
