Abstract:
1. A method of forming a semiconductor device, comprising: providing a substrate having a surface; forming a first coil structure over the surface of the substrate, the first coil structure having a height greater than a skin current depth of the first coil structure defined as a depth which current reduces to 1/(complex permittivity) of a surface current value; forming a second coil structure over the surface of the substrate adjacent to the first coil structure in a plane parallel to the surface of the substrate, the second coil structure having a height greater than a skin current depth of the second coil structure defined as a depth which current reduces to 1/(complex permittivity) of a surface current value; and forming a third coil structure over the surface of the substrate adjacent to the second coil structure opposite the first coil structure in a plane parallel to the surface of the substrate, the third coil structure having a height greater than a skin current depth of the third coil structure defined as a depth which current reduces to 1/(complex permittivity) of a surface current value.
