Abstract
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.
