Claim 0:
1. A fingerprint sensor package, comprising:
a film substrate;
an interconnection substrate on the film substrate;
a semiconductor chip on the interconnection substrate;
a conductive structure on the interconnection substrate, the conductive structure laterally isolated from direct contact with the semiconductor chip; and
an interposer substrate on both the semiconductor chip and the conductive structure, such that
the semiconductor chip and the conductive structure are between the interconnection substrate and the interposer substrate in a vertical direction that is perpendicular to a top surface of the interconnection substrate, and
the conductive structure and the semiconductor chip at least partially overlap in a horizontal direction that is parallel to the top surface of the interconnection substrate,

wherein the conductive structure includes a first conductive structure and a second conductive structure, the first conductive structure and the second conductive structure electrically separated from each other,
wherein the interposer substrate includes
a first sensing pattern electrically connected to the first conductive structure, and
a second sensing pattern on a top surface of the first sensing pattern, the second sensing pattern electrically connected to the second conductive structure such that the first and second sensing patterns are electrically coupled to the interconnection substrate via different conductive structures of the first and second conductive structures,

wherein the second sensing pattern is vertically isolated from direct contact with the first sensing pattern, and
wherein a longitudinal axis of the second sensing pattern is parallel to a direction crossing a longitudinal axis of the first sensing pattern, when viewed in a plan view, such that at least a portion of the first sensing pattern and at least a portion of the second sensing pattern overlap each other in the vertical direction at an intersection point.
