Abstract: A method of forming a semiconductor device is presented. A conductor is embedded within a substrate, wherein the substrate contains a non-conducting material. The backside of the substrate is ground to a thickness wherein at least 1 ?m of the non-conducting material remains on the backside covering the conductor embedded within the substrate.
