Abstract:
1. A sliding type thin fingerprint sensor package comprising: a substrate defined as a sliding region and a conductive portion, the substrate comprising: a dielectric layer having an upper surface, a lower surface and a window penetrating the upper surface and the lower surface; a circuit layer having a first surface, a second surface, a plurality of external contact pads, at least one internal contact pad and at least one electrostatic conductive pad, wherein the external contact pads and the electrostatic conductive pad are formed on the upper surface of the dielectric layer, the electrostatic conductive pad is close to the window of the dielectric layer; and a first passivation layer formed on the first surface of the circuit layer, the first passivation layer having a plurality of first openings to expose the external contact pads and at least one second opening to expose the electrostatic conductive pad and the window of the dielectric layer; wherein the electrostatic conductive pad and the window are located at the sliding region, the external contact pads are located at the conductive portion; and a fingerprint sensor chip electrically connected with the internal contact pad, the fingerprint sensor chip having an active surface, a back surface and a sensing region formed on the active surface and exposed via the second opening of the first passivation layer and the window of the dielectric layer.
