abstract
Energy flux measurements were carried out using a passive thermal probe during sputtering of titanium in a reactive Ar/O2 atmosphere with a rotating cylindrical magnetron. The data were collected 90° around the cylindrical magnetron cathode. The rectangular voltage pulses had a duration of either 5 or 20 μs and target voltage was set to 600V in order to reach a timeaveraged power density over the racetrack of 30 W/cm². As a reference, the energy flux was also measured during DC magnetron under the same working conditions. The energy flux per adparticle was calculated by measuring the deposition rate for all sputter modes and regimes. The lowest deposition rate was measured during reactive HiPIMS, with 20μs-long pulses. However the highest energy per adparticle was measured for that particular case. This result can be understood based on the increased ion and electron fluxes on the probe surface during the HiPIMS experiments. A possible contribution to the energy flux could also originate from the presence of fast oxygen ions (0-) emitted from the target surface and accelerated in the cathode sheath. A difference in the angular distribution of the energy deposited per arriving adparticle is noticed when comparing the dc and the HIPIMS discharges. The dc mode has a maximum arriving energy per adparticle at around 50°, while the maximum is located at 60° for the HIPIMS mode.
