Abstract
Neutral CF3 and CF2 radicals in a hollow cathode DC CF4 discharge were first detected with a quadrupole mass spectrometer, using the threshold ionization technique. At CF4 pressure of 27 Pa, the densities of both radicals were measured as a function of discharge current over a range of 20-50 mA. CF4 pressure dependences of these radical densities were also measured over a CF4 pressure range of 27-80 Pa. The results showed that the CF3 and CF2 radical densities increased with discharge current. The CF3 radical density increased with CF4 pressure. On the other hand, the CF2 radical density increased up to 40 Pa and then tended to be decrease.
