Abstract:
1. A method of forming an inductor, comprising: depositing a layer of magnetic material on a substrate; depositing a non-magnetic insulating layer on the magnetic material layer; forming a substantially circular open inductor pattern on the non-magnetic insulating layer and above the magnetic material layer, the open inductor pattern having an outer edge, wherein the open inductor pattern is unconnected to the layer of magnetic material, and wherein forming the substantially circular open inductor pattern includes forming a first conductive pattern and forming a second conductive pattern over the first conductive pattern and coupled to the first conductive pattern; depositing a second non-magnetic insulating layer on the open inductor pattern; and depositing a second magnetic material layer on the second non-magnetic insulating layer, wherein the second magnetic material layer is between the first conductive pattern and the second conductive pattern.
