Chemistry studies of sf6 gas/CF4, Sulfr hexafluoride/O2 and CF4/O2 gas phase

The addition of CF 4 in SF 6 plasma reduces monotonically the F concentration when compared with the SF 6 /O 2 and CF 4 /O 2 plasmas that promotes an increase of F for low O 2 concentrations. This effect shows the importance of oxygen species in the dissociative processes of the fluorine-based plasma also for this type of plasma reactor.Get price
