Process stabilization by peak current regulation in reactive high-power impulse magnetron sputtering of hafnium nitride
A simple and cost effective approach to stabilize the sputtering process in the transition zone during reactive high-power impulse magnetron sputtering (HiPIMS) is proposed. The method is based on real-time monitoring and control of the discharge current waveforms. To stabilize the process conditions at a given set point, a feedback control system was implemented that automatically regulates th...
متن کاملHysteresis-free reactive high power impulse magnetron sputtering
High power impulse magnetron sputtering (HIPIMS) of an Al target in Ar/O2 mixtures has been studied. The use of HIPIMS is shown to drastically influence the process characteristics compared to conventional sputtering. Under suitable conditions, oxide formation on the target as the reactive gas flow is increased is suppressed, and the hysteresis effect commonly observed as the gas flow is varied...

متن کاملUnderstanding deposition rate loss in high power impulse magnetron sputtering
The lower deposition rate for high power impulse magnetron sputtering (HiPIMS) compared to direct current magnetron sputtering for the same average power is often reported as a drawback. The often invoked reason is back-attraction of ionized sputtered material to the target, due to a substantial negative potential profile from the location of ionization towards the cathode. Emitting and swept L...
