Numerical simulations were conducted to investigate the different potential distributions for an insulating sample on a conducting target holder. The surface potential on the sample was assumed to be 0, 1/5, 3/5 and 5/5 of the applied bias, respectively. It was found that the simulation results indicate that the plasma sheath configuration changes considerably and a low potential in the central zone leads to a lower ion dose.
