Abstract:
An integrated inductor, comprising:a semiconductor material body; an insulating layer formed on the semiconductor material body, a coil of conductive material extending above and spaced away from said insulating layer by an air gap; and a bracket supporting the coil on said insulating layer, said bracket having a first support portion that supports the coil above said air gap and a second support portion extending from said coil to said insulating layer and from a central area to a peripheral area of said bracket, said second support portion including an electrical isolation portion that insulates peripheral portions of the coil from the semiconductor material body, wherein said electrical isolation portion is made of a dielectric material, and surrounds above and laterally an electrical connection line extending on said insulating layer, said connection line being on substantially a same level as said air gap and connected to a central terminal of said coil through a contact region extending through an aperture of said bracket.
