The image sensor package includes a first substrate comprising a via hole therein, a driving circuit and a first conductive pad thereon. A second substrate comprising a photosensitive device and a second conductive pad thereon is bonded to the first substrate, so that the driving circuit, formed on the first substrate, can electrically connect to and further control the photosensitive device, formed on the second substrate.
