ABSTRACT:
A semiconductor device increases the efficiency of the inductor having a three-dimensional spiral coil and increases the inductance value without requiring any special steps. The semiconductor device includes semiconductor elements and first, second and third metal wire layers to be used for the configuration of the semiconductor elements, a core disposed on the second metal wire layer, and a coil wherein a plurality of pieces of the first metal wire layer and a plurality of pieces of the third metal wire layer connected to the pieces via the connection holes are connected in series to define a spiral surrounding the core.
