Abstract
A fingerprint sensor is provided. The fingerprint sensor includes a multi-layer printed circuit board (PCB), a fingerprint sensing die and a molding compound. The multi-layer PCB includes a bottom dielectric layer, at least one intermediate dielectric layer disposed on the bottom dielectric layer, a top dielectric layer disposed on the intermediate dielectric layer and a trench. The trench is formed by digging out a portion of the intermediate dielectric layer and a portion of the top dielectric layer. The fingerprint sensing die is disposed in the trench of the multi-layer PCB and mounted on an upper surface of the bottom dielectric layer of the multi-layer PCB. The fingerprint sensing die includes a sensing array capable of sensing fingerprint information of a user. The fingerprint sensing die is covered by the molding compound, and the trench of the multi-layer PCB is filled with the molding compound.
