US 7,884,697 B2 · Tunable embedded inductor devices

Abstract

The invention provides tunable embedded high frequency inductor devices. The inductor device comprises a dielectric substrate. A first conductive line is disposed on a first surface of the dielectric substrate. A second conductive line is disposed on a second surface of the dielectric substrate. An interconnection is disposed perforating the dielectric substrate and connecting the first conductive line with the second conductive line. A coupling region is defined between the first and the second conductive lines. A conductive plug connecting the first conductive line and the second line is disposed in the coupling region. Alternatively, an opening is disposed in the first and second conductive lines to tune inductance of the inductor.
