Abstract:
1. An apparatus, comprising: a source simultaneously producing first plasma, which includes a first species of ions, and second plasma, which includes a second, differing, species of ions; an accelerator system including an analyzer magnet, which cooperate to simultaneously: (i) accelerate the first and second plasma along an initial axis, (ii) alter a trajectory of the first species of ions from the first plasma, thereby producing at least one first ion beam along a first axis, which is transverse to the initial axis, and (iii) alter a trajectory of the second species of ions from the second plasma, thereby producing at least one second ion beam along a second axis, which is transverse to the initial axis and the first axis; and a beam processing system operating to simultaneously direct the first and second ion beams toward a semiconductor wafer such that the first and second species of ions bombard an implantation surface of the semiconductor wafer to create an exfoliation layer therein.
