A process for the fabrication of aluminum metallixed pyrolytic grapbitc sputtering targets.
A de\ ice for plating a wafer in which the lower surface of the circumferential edge of the wafer is held by a holding means onlo a posittoning base portion formed in an opening portion of a plating bath and a plating fluid is applied onto the lower SW face of the wafer- for plating. characterized in that the holding means comprises an air bag, which is adapted to constrain only the upper surface of the circumferential edge of the wafer at an expanded state and releases the constraint by contracting to restore an initial configuration at a nonexpanded state
