Claim 14:
15. A method of processing a wafer with an ion beam, the method comprising:
in a processing chamber, performing a first pass scan by exposing the wafer to an ion beam according to a first planar motion of the wafer, the wafer being held at a first twist angle and a first tilt angle during the first pass scan, the first twist angle being relative to a reference axis of a rotatable feedthrough of the processing chamber, the first tilt angle being relative to a plane normal to the ion beam; and
in the processing chamber, performing a second pass scan by exposing the wafer to the ion beam according to a second planar motion of the wafer, the wafer being held at a second twist angle and a second tilt angle during the second pass scan.
