Abstract
A sensor semiconductor device and a method for fabricating the same are proposed. A sensor chip is mounted on a substrate, and a dielectric layer and a circuit layer are formed on the substrate, wherein the circuit layer is electrically connected to the substrate and the sensor chip. The dielectric layer is formed with an opening for exposing a sensor region of the sensor chip. A light-penetrable lid covers the opening of the dielectric layer, such that light is able to penetrate the light-penetrable lid to reach the sensor region and activate the sensor chip. The sensor chip can be electrically connected to an external device via a plurality of solder balls implanted on a surface of the substrate not for mounting the sensor chip. Therefore, the sensor semiconductor device is fabricated in a cost-effective manner, and circuit cracking and a know good die (KGD) problem are prevented.
