PROBLEM TO BE SOLVED: To solve a problem that an internal inductor of a semiconductor device is apt to malfunction or stop operating since an influence of lines of magnetic force that an inductor generates on the internal inductor is strong because of a short distance between the internal inductor and inductor. SOLUTION: The inductor 50 and internal inductor 12 are formed not superposing each other along the thickness of a silicon substrate 10. Consequently, the distance between the inductor 50 and internal inductor 12 when they do not superpose each other along the thickness of the silicon substrate 10 is longer than that when they superpose each other. Consequently, the influence of lines of magnetic force that the inductor 50 generates on the internal inductor 12 is reduced. Consequently, malfunction and operation stopping of the internal inductor 12 of the semiconductor device 1 can be reduced. COPYRIGHT: (C)2009,JPO&INPIT
