Claim Text:
1. A semiconductor structure, comprising: a substrate; a plurality of parallel first conductive layers formed in the substrate, a top surface of a first conductive layer levelling with a top surface of the substrate; a composite magnetic structure having a plurality of magnetic layers and a plurality of insulation layers with a sandwich arrangement formed on a portion of a surface of the substrate and portions of surfaces of the plurality of the first conductive layers, each magnetic layer being sandwiched between two insulation layers; a plurality of first conductive vias and a plurality of second conductive vias formed on the first conductive layers at both sides of the composite magnetic structure; and a plurality of second conductive layers formed 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.
