Claim:
1. A method for fabricating a semiconductor structure, comprising: providing a substrate; forming a plurality of parallel first conductive layers formed in the substrate and having a top surface exposed; forming a composite magnetic structure having a plurality of magnetic layers and a plurality of insulation layers with a sandwich arrangement on a portion of the surface of the substrate and portions of surfaces of the plurality of first conductive layers; forming a plurality of first conductive vias and a plurality of second conductive vias on the plurality of first conductive layers at both sides of the first conductive layers respectively; and forming a plurality of second conductive layers on a top surface of the composite magnetic structure, top surfaces of the first conductive vias, and top surfaces of the second conductive vias to form at least one coil structure wrapping around the composite magnetic structure.
