The effects of oxygen flooding on the sputter and ionization yield of
Si and SiO2 have been investigated. Additional processes in sputtering
and ionization may be introduced by oxygen flooding beyond a simple c
hemical adsorption and knock-on process, leading to a larger reduction
in sputter yield and a further enhancement in ionization yield for si
licon sputtered from a Si substrate as compared to the values for sili
con dioxide. A transient, particularly for the sputter yield, still re
mains, implying that the transient reduction is not as complete as des
ired. (C) 1997 American Vacuum Society.
