Abstract
An apparatus and method for fabricating high value inductors embedded on semiconductor integrated circuit. The apparatus and method involve forming a conductor on the semiconductor substrate. Once the conductor is formed, a polymer material is provided on the substrate surrounding the conductor. The polymer material contains a ferromagnetic material so that the permeability of the polymer is greater than one. In various embodiments, the ferromagnetic material may be any one of a number of different high permeable materials such as iron oxide, zinc, manganese, zirconium, samarium (SA), neodymium (NA), cobalt, nickel or a combination thereof.
