Claim 14:
15. A fingerprint sensor package, comprising:
a film substrate including a coupling terminal;
an interconnection substrate on the film substrate;
a connection solder between the film substrate and the interconnection substrate, the connection solder electrically connected to the coupling terminal;
a lower under-fill layer between the film substrate and the interconnection substrate, the lower under-fill layer covering a side surface of the connection solder;
a semiconductor chip on a top surface of the interconnection substrate;
bumps between the top surface of the interconnection substrate and the semiconductor chip;
a passive device on the top surface of the interconnection substrate, the passive device laterally isolated from direct contact with the semiconductor chip;
conductive structures on the top surface of the interconnection substrate, the conductive structures laterally isolated from direct contact with both the semiconductor chip and the passive device;
an interposer substrate on both the semiconductor chip and the conductive structures, the interposer substrate electrically connected to the conductive structures; and
a mold layer between the interconnection substrate and the interposer substrate, the mold layer covering side surfaces of the conductive structures, the semiconductor chip, and the passive device,
wherein the interposer substrate includes
first sensing patterns,
second sensing patterns on top surfaces of the first sensing patterns, the second sensing patterns vertically isolated from direct contact with the top surfaces of the first sensing patterns; and
a protection layer covering the second sensing patterns.
