Abstract

A semiconductor apparatus comprises a substrate, a semiconductor chip fixedly secured on one side of the substrate, a spirally shaped coil formed on the other side of the substrate and electrically connected to the semiconductor chip, and a conductive pattern formed on a surface of the one side of the substrate facing to the semiconductor chip for stabilizing an inductance characteristic of the coil.
