  • Patent number: 8053864
    Abstract: An inexpensive variable inductor has inductance value continuously changeable without reducing a Q value. When a control voltage is applied to a control terminal of a MOS transistor from a power supply, a continuity region is formed in a channel, and a region between main terminals becomes conductive. When the control voltage is changed, length of the continuity region in the channel is changed. This changes length of a path area of an induced current, flowing in an induced current film. Thus, the amount of induced current is increased or decreased. Therefore, when the control voltage of the MOS transistor is changed, the inductance value of the coil is continuously changed.

  • Patent number: 7888227
    Abstract: Integrated circuit inductors (5) are formed by interconnecting various metal layers (10) in an integrated circuit with continuous vias (200). Using continuous vias (200) improves the Q factor over existing methods for high frequency applications. The contiguous length of the continuous vias should be greater than three percent of the length of the inductor (5).

    Abstract: A first insulating film includes five extension lines formed between connection pad portions of adjacent two predetermined wiring lines. The first insulating film also includes peripheral portions of the adjacent two connection pad portions on both sides of the five extension lines. A second insulating film made of a polyimide resin or the like is formed on the upper surface of the first insulating layer by a screen printing method or ink jet method. Since a short circuit may be easily caused by electromigration in a region where the five extension lines are parallel to another, the short circuit due to the electromigration can be prevented by covering only that region with the second insulating film. Accordingly, the region where the second insulating film is formed can be as small as possible, and the semiconductor wafer does not easily warp.
