Patent ID: 8624701

Claim:
A package structure, comprising: a substrate, comprising a top surface, a bottom surface and a lateral surface; a coil disposed in the substrate, wherein the coil comprises: a first plurality of through holes disposed in the substrate in a first sequence; and a second plurality of through holes disposed in the substrate in a second sequence, wherein each of the first plurality of through holes has a corresponding through hole of the second plurality of through holes, wherein each of the first plurality of through holes is electrically connected to the corresponding through hole of the second plurality of through holes via the bottom surface; and each of the first plurality of through holes is electrically connected to an adjacent through hole of the corresponding through hole in the second sequence via the top surface so as to form the coil; a conductive pattern wrapping a first surface of the substrate, wherein the first surface comprises a portion of the top surface, a portion of the bottom surface and a portion of the lateral surface, wherein the coil is electrically connected to the conductive pattern; and a first conductive element disposed over the lateral surface of the substrate, wherein the first conductive element is electrically connected to the conductive pattern.
