Zusammenfassung:	A method and apparatus for fabricating a wafer spacing mask on a workpiece support chuck. Such apparatus is a central body containing a plurality of apertures that is positioned atop the workpiece support chuck and an outer ring shaped body positioned on a flange of the workpiece support chuck while material is deposited onto the apparatus and through the apertures onto chuck. Upon completion of the deposition process, the central body and ring shaped body are removed from the workpiece support chuck leaving deposits of the material to form the wafer spacing mask.
