摘要： A thin film transformer which is fabricated on a substrate includes first and second thin film coils. One of the coils includes either of at least two spiral shaped coil parts that are disposed below an insulation layer and either of at least two spiral shaped coil parts that are disposed above the insulation layer, the coil parts being connected through a connection hole in the insulation layer, with terminals for the coil being located outside the outer loops of the coil parts. The other of the coils includes other coil parts that are connected through a connection hole in the insulation layer, with terminals again being located outside the outer loops of the coil parts. With this configuration, the first and second thin film coils have terminals that are located outside of the outer loops of the coils. Side-by-side transformers whose primaries and secondaries are connected so as to form a single transformer are also disclosed.
