Claim:
1. A fingerprint identification device, comprising: a first dielectric layer having a first surface and a second surface opposite thereto; a fingerprint sensing chip having a top surface and a bottom surface opposite thereto, the fingerprint sensing chip being disposed on the first surface with the bottom surface projecting towards the first surface, the fingerprint sensing chip including a drive transmission pad, the drive transmission pad being disposed on the top surface; a packaging layer covering the top surface of the fingerprint sensing chip and the first surface of the first dielectric layer, the packaging layer defining a first via hole, the first via hole being corresponding to the drive transmission pad; a first redistribution layer disposing on the packaging layer, the first distribution layer connecting electrically to the drive transmission pad via the first via hole; a second dielectric layer covering the packaging layer and the first redistribution layer, the second dielectric layer defining a second via hole; a second redistribution layer disposing on the second dielectric layer, the second redistribution layer defining a looped pattern, while connecting electrically to the first redistribution layer via the second via hole; and a third dielectric layer covering the second dielectric layer and second redistribution layer.
