  • Planar spiral inductor structure having enhanced Q value
    Patent number: 7592891
    Abstract: Within a method for fabricating an inductor structure there is first provided a substrate. There is then formed over the substrate a planar spiral conductor layer to form a planar spiral inductor, wherein a successive series of spirals within the planar spiral conductor layer is formed with a variation in at least one of: (1) a series of linewidths of the successive series of spirals; and (2) a series of spacings of the successive series of spirals. The method contemplates a planar spiral inductor structure fabricated in accord with the method. A planar spiral inductor structure fabricated in accord with the method is characterized by an enhanced Q value of the planar spiral inductor structure.
    Type: Grant
