Several phenomena in HiPIMS discharge are thus far dierent from other magnetron discharges, e.g DC, RF and pulsed-DC discharges. The physics of HiPIMS discharges has been reviewed by several authors e.g. Helmersson et al. [1], Sarakinos et al. [26], Anders [38], Lundin and Sarakinos [25] and Gudmundsson et al. [14].Base on these review articles, a brief overview of the physics involved with HiPIMS is summarised as the following paragraphs.
