DETAILED DESCRIPTION

FIG. 1Aillustrates a three-dimensional (3D) view of a semiconductor package device1in accordance with one embodiment of the present disclosure. The semiconductor package device1has six surfaces, a bottom surface10, four lateral surfaces11,12,13,14and a top surface15. The top surface15is opposite to the bottom surface10. Four lateral surfaces11,12,13,14are extended between the top surface15and the bottom surface10and are substantially perpendicular to the top surface15and the bottom surface10. The lateral surface11is opposite to the lateral surface12and substantially perpendicular to the lateral surfaces13,14.

The bottom surface10of the semiconductor package device1has a conductive pattern10a. The conductive pattern10amay be any conductive material, such as copper, nickel, aluminum, tungsten, titanium, any combination thereof, or the like. As shown inFIG. 1A, the conductive pattern10ahas a plurality of conductive metals. The conductive metals of the conductive pattern10aare separated from each other and are substantially parallel to each other.

The lateral surface11of the semiconductor package device1has a conductive pattern11a. The conductive pattern11amay be any conductive material, such as copper, nickel, aluminum, tungsten, titanium, any combination thereof, or the like. The conductive pattern11ahas a plurality of separated conductive metals. Each conductive metal of the conductive pattern11aare connected with the corresponding conductive metals of the conductive pattern10a.

The lateral surface12of the semiconductor package device1has a conductive pattern12a. The conductive pattern12amay be any conductive material, such as copper, nickel, aluminum, tungsten, titanium, any combination thereof, or the like. The conductive pattern12ahas a plurality of separated conductive metals. Each conductive metal of the conductive pattern12aare connected with the corresponding conductive metals of the conductive pattern10a.

The conductive pattern10aon the bottom surface10, the conductive pattern11aon the lateral surface11and the conductive pattern12aon the lateral surface12jointly define a coil, an inductor or a transformer. In some embodiments of the present disclosure, the coil, the inductor or the transformer can be connected to circuits (not shown) integrated in the semiconductor package device1to form a transmitter or a receiver. Alternatively, the coil, the inductor or the transformer can be connected to circuits exterior to the semiconductor package device1to form a transmitter or a receiver.

Based on the electromagnetic induction theory, two inductors should be placed to be parallel to each other to get a maximum power interchange. For example, to let a receiver to receive a maximum power from a transmitter, the inductor of the receiver should be arranged to be parallel to that of the transmitter. That is, the inductor of the receiver should be aligned with that of the transmitter. In some embodiments, the semiconductor package device has a conductive pattern only on one surface, and thus the magnetic field of the inductor of the semiconductor package device can be only transmitted or received in one direction. Therefore, the inductor of the receiver should be aligned with that of the transmitter to receive the maximum magnetic field, resulting in that the design or the placement of the transmitter and the receiver is not flexible.

As shown inFIG. 1A, because the semiconductor package device1has conductive patterns on three surfaces, it can receive or transmit magnetic field in three directions (i.e., the direction perpendicular to the bottom surface10, the direction perpendicular to the lateral surface11and the direction perpendicular to the lateral surface12). In comparison with the semiconductor package device having only one surface with a conductive pattern, the semiconductor package device1shown inFIG. 1Acan be design or placed more flexible to receive or transmit the magnetic field. In addition, the semiconductor package device1shown inFIG. 1Ahas better communication quality in the case that the transmitter and the receiver are misaligned.
