A fuel tank shield is provided for mounting between a fuel tank and a rotating drive shaft of the type having a generally smooth cylindrical outer surface from which a hard edge extends adjacent the fuel tank shield. The powder prevents noise of inner lips of the glass run. In the event of a changed relative position between the two housing parts, the damping occurs via the secondary damping element. The spacer layer may include a protective sublayer, like a layer of Ag, below the IZO layer to prevent oxidation of the reference layer from the oxygen in the IZO layer. A technique is described hereafter where the nature of the wet anisotropic etch process is used for fabrication of electrostatic transducers and in particular electrostatic comb drive actuators and sensors. Portions of the metallic capping layer between the damascene conductive wiresstuds are removed to form a metallic cap on each damascene conductive wirestud and to conductively isolate one or more of the damascene conductive wiresstuds.
