An image sensor includes a first substrate, readout circuitry, an electrical junction region, a metal interconnection and an image sensing device. The readout circuitry is formed on and/or over the first substrate and the electrical junction region is formed in the first substrate and electrically connected to the readout circuitry. The metal interconnection is electrically connected to the electrical junction region. The image sensing device is formed on and/or over the metal interconnection.
