Emission and Electrical Measurements to Assess Actinometry in

In SiC etching plasma devices, we have recorded plasma emission from Ar, F and O atoms in Sulfr hexafluoride/Ar/O2 RF discharges as a function of pressure, input power and mixture fraction. At fixed power, the emission intensities rise nearly linearly with increasing pressure between 100 and 300 mTorr; with pressure increases to 600 mTorr, the emission intensity rolls off due to the increase in collisionalGet price

insulating gas clearly increased from 37.79 to 95.68% because of an increase in power from 5 to 20 W. When the power exceeded 40 W, η insulating gas exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η sf6 gas was ~10% less than when no oxygen was added (from 28.61 to 86.09% as the power rose from 5 to 20 W).
