Abstract

Imperfections of the ion implantation equipment may lead to the co-implantation of unwanted impurities. Such imperfections are, for example, insufficient mass separation caused by improper focusing, or magnet current or high-voltage fluctuations. Another source for impurities is the sputtering of machine components as they are struck by the ion beam.
