Abstract:
A method for aligning a wafer to a first aligned position and aligning a cathode to a second aligned position, comprising the steps of:lowering a wafer towards said first aligned position; making contact of said wafer to a first alignment surface when said wafer is lowered towards said first aligned position and said wafer is horizontally misaligned with said first aligned position to cause said wafer to horizontally align with said first aligned position; after said wafer is in said first aligned position, lowering said cathode towards said second aligned position; and making contact of said cathode to a second alignment surface when said cathode is lowered towards said second aligned position and said cathode is horizontally misaligned with said second aligned position to cause said cathode to horizontally align with said second aligned position whereat said cathode is at a predetermined position with respect to said wafer.
