    • 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.

    • To improve high frequency characteristics of a transformer in a switching power supply device and to reduce its size, the switching power supply device is formed of a voltage converting section in a thin-film laminated structure, a single semiconductor chip and a wiring layer situated between the voltage converting section and the single semiconductor chip. All the active elements including switching elements and voltage controlling sections are incorporated into the semiconductor chip and are connected to the voltage converting section through the wiring layer. To reduce the effects other than inductance of the electrical components, a thin film transformer is formed of a spiral-shaped primary coil and secondary coil formed on a substrate. The primary and secondary coils are arranged so that phases of forming cycles in the radial direction are different to have a staggered relation. Accordingly, the capacity of the parasitic capacitors between the primary coil and the secondary coil is very small.
    • 为了改善开关电源装置中的变压器的高频特性并减小其尺寸,开关电源装置由薄膜层压结构中的电压转换部分,单个半导体芯片和位于 电压转换部和单个半导体芯片。 所有包括开关元件和电压控制部分的有源元件并入半导体芯片中,并通过布线层连接到电压转换部分。 为了减小电气部件的电感以外的效果,薄膜变压器由形成在基板上的螺旋状的初级线圈和次级线圈形成。 初级线圈和次级线圈被布置成使得在径向方向上的成形周期的相位不同以具有交错关系。 因此,初级线圈和次级线圈之间的寄生电容的容量非常小。
