Results on Plasma Immersion Ion Implantation
(PIII) of nitrogen ions into a metal surface using
microwave plasma source are described. Preliminary
results in our benchtop PI11 system with microwave
source showed successful N+ implantation in an A1
sample but indicated the necessity of better plasma
optimization and confirmed a need for a high repetition
rate, negative high voltage pulser which is presently
under development.
