Abstract: Disclosed is a method of forming a semiconductor device having circuit components in a semiconductor substrate which are electrically isolated from each other by a layer of etch resistant material. During the fabrication of the device the etch resistant material acts as an etch barrier that prevents the etchant from removing any portion of the semiconductor substrate used for the circuit components.
