Abstract
Multiple intertwined inductor coils combine to form one or more transformer devices of a semiconductor device. The intertwined inductor coils are formed of only two metallization layers and vias coupling the layers. The inductor coils are vertically oriented and include a magnetic axis parallel to the substrate surface. A plurality of metal wires are provided on both a first device level and a second device level. Each of the metal wires on the first device level is coupled to two wires on the second device level and forms a first inductor coil. The two metal wires on the second device level that form part of the first inductor coil, are separated by a third wire that is coupled to two different first device level metal wires and forms part of a different second inductor coil intertwined with the first inductor coil.
