A fabrication method of high performance integrated inductor devices using a substrate conversion technique is disclosed. By employing the trench-shaped porous silicon with high insulating property, the lossy characteristic of the silicon substrate is essentially to minimize. Also, by employing the conductive doped layer interposed between the porous silicon layer and the silicon substrate, the parasitic capacitance between metal lines and the silicon substrate is remarkably decreased. The present invention allows fabrication of high performance integrated inductors having high quality factor. Also, this invention prevents mutual-coupling between the silicon substrate and metal lines. As a result, integrated inductor devices according to this invention is readily adaptable for use in radio frequency integrated circuit (RF IC).

Methods for foming an inductor devices used for impedance matching in the radio frequency integrated circuits are disclosed. In the integrated inductor device according to the present invention, an additional electrode is arranged in surroundings of an inductor metal line, and the reverse bias voltage is applied to the region between the substrate and the electrode so as to form a depletion layer. Therefore, the substrate biasing is effected and thus an inductor having improved performance can be formed by decreasing the parasitic capacitance between the inductor metal line and the substrate. The present invention can also be applied to another semiconductor device having metal lines and pads.
