摘要
Emission spectroscopy in the visible and UV during ionised physical vapour deposition has been used to investigate the effects of a secondary inductive coil on magnetron sputter deposition of metal cathode targets. Atomic and ionic emission lines of the sputtering gas and sputtered metal were identified, and line intensity measurements were used to investigate the sputtering, excitation and ionisation of metal in the magnetron and RF plasmas. Ionisation of sputtered material by the magnetron plasma was found to be significant, and it was found that sputtering of material from the RF coil could be eliminated by the insertion of a capacitor in the external RF power circuit between the coil and earth.
