An image sensor package and method for fabricating the same is provided. 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. A solder ball is formed on a backside of the first substrate and electrically connects to the via hole for transmitting a signal from the driving circuit. Because the photosensitive device and the driving circuit are fabricated individually on the different substrates, fabrication and design thereof is more flexible. Moreover, the image sensor package is relatively less thick, thus, the dimensions thereof are reduced.

Image sensor package

The invention provides an image sensor package and method for fabricating the same. The image sensor package comprises a first substrate comprising a sensor device thereon and a hole therein. A bonding pad comprising a first opening is formed on an upper surface of the first substrate. A second substrate comprising a spacer element with a second opening therein is disposed on the first substrate. A conductive plug is formed in the hole and passes through the first and second openings to the second substrate to electrically contact with the bonding pad. A conductive layer is formed on a lower surface of the first substrate and electrically connects to the conductive plug. A solder ball is formed on the conductive layer and electrically connects to the bonding pad by the conductive plug. The image sensor package further comprises a second substrate bonding to the first substrate. The image sensor package is relatively less thick, thus, the dimensions thereof are relatively reduced.
