Claim 10:
11. A coil module, comprising:
a substrate, including a first magnetic conductive element, wherein the first magnetic conductive element has a first surface and a second surface parallel to each other, wherein the first surface and the second surface have a distance greater than zero in a direction perpendicular to the first surface;
a first coil, disposed on the substrate, wherein when viewed in the direction perpendicular to the first surface, the first coil overlaps at least a portion of the first surface;
a second coil, disposed on the substrate, wherein when viewed in the direction perpendicular to the first surface, the second coil overlaps at least a portion of the second surface; and
a third coil, disposed on the first coil, wherein when viewed in the direction perpendicular to the first surface, the third coil overlaps at least a portion of the first surface;
wherein the first coil is electrically independent from the second coil;
wherein the third coil is in contact with the first coil, and the third coil is not in contact with the second coil.
