Abstract
The structure includes a semiconductor chip connected to a substrate via one or more solder balls. The semiconductor chip includes one or more on-chip metal winding. The structure includes a first ferromagnetic core. The first ferromagnetic core is located below the semiconductor chip and above the substrate. The structure includes a second ferromagnetic core. The second ferromagnetic core is located above the semiconductor chip. The first ferromagnetic core and the second ferromagnetic core create a magnetic loop.
