Abstract

Systems and methods of an ion implant apparatus include an ion source for producing an ion beam along an incident beam axis. The ion implant apparatus includes a beam deflecting assembly coupled to a rotation mechanism that rotates the beam deflecting assembly about the incident beam axis and deflects the ion beam. At least one wafer holder holds target wafers and the rotation mechanism operates to direct the ion beam at one of the at least one wafer holders which also rotates to maintain a constant implant angle.
