Abstract:
1. A fabrication method of a sensor semiconductor device, comprising the steps of: mounting at least one sensor chip on a surface of at least one substrate, the sensor chip having an active surface and an opposed non-active surface, with the non-active surface of the sensor chip being attached to the substrate, wherein a plurality of electrical contacts are formed on the surface of the substrate, and a sensor region and a plurality of electrode pads are formed on the active surface of the sensor chip, and wherein an edge of the active surface of the sensor chip is formed with a chamfer; forming a transparent cover on the sensor region of the sensor chip; applying a dielectric layer on the substrate and the sensor chip, wherein the electrical contacts of the substrate, the electrode pads of the sensor chip and the transparent cover are exposed from the dielectric layer; forming a circuit layer on the dielectric layer, wherein the circuit layer is electrically connected to the electrical contacts of the substrate and the electrode pads of the sensor chip; and applying a protective layer on the circuit layer, with the transparent cover being exposed from the protective layer, wherein the protective layer is a solder mask layer.
