Patent ID: 8339230

Claim:
An inductor element formed in a multiple layer lead structure comprising: a lead, an insulative layer that insulates leads above and below, and a via provided in the insulative layer and connecting leads above and below, wherein lead layers are multiply laminated layers, comprising at least a portion of at least a pair of vertically adjacent leads which are coiled leads; wherein the coiled leads are connected in series, wherein at least two of the coiled leads comprise a shape having one wind; wherein a shape having said one wind does not completely coil around and has a notch in a portion thereof; wherein current directions of vertically adjacent coiled leads are the same by a via provided on an end portion thereof, and form a serial inductance; and wherein an inter-lead capacitance of the vertically adjacent coiled leads is larger than an inter-lead capacitance between other coiled leads formed in the same lead layer.
