Abstract
A semiconductor package according to some examples of the disclosure may include a first body layer, a transformer that may comprise one or more inductors, coupled inductors, or inductive elements positioned above the first body layer. A first ground plane is on a top of the first body layer between the first body layer and the inductive element. The first ground plane may have conductive lines generally perpendicular to a magnetic field generated by the inductive element, and a second ground plane on a bottom of the first body layer opposite the first ground plane. The first and second ground planes may also provide heat dissipation elements for the semiconductor as well as reduce or eliminate eddy current and parasitic effects produced by the inductive element.
