biased by negatively voItage pulse w i th a f inite rise time in the pIasma source ion implantation. Resul ts
show that the time-dependent sheath consisted of two pû ts: the ion man ix sheath deveIOPInent during
the pulse r ise time and the dynamic sheath motion af ter attaini ng the hl Il puIse. T he ion matrix sheath
