Circuit board and method of manufacturing the same
A circuit board includes a substrate, a first magnetic structure, a first dielectric layer and an inductive coil. The substrate has a top surface and a bottom surface. The first magnetic structure is disposed on the top surface of the substrate. The first dielectric layer covers the substrate and the first magnetic structure. The inductive coil includes a first interconnect, a second interconnect and a plurality of conductive pillars. The first interconnect is disposed on the first dielectric layer. The second interconnect is disposed on the bottom surface of the substrate. The conductive pillars connect the first interconnect and the second interconnect. The first interconnect, the second interconnect and the conductive pillars form a helical structure surrounding the first magnetic structure.
