From DCMS To HIPIMS Based on “Structure Zone Model” - Thornton, J.Vac. Sci. Technol. 11 (1974) 666
From DCMS To HIPIMS To enhance Ions production Higher power Higher Plasma density and higher cathode current Overheating and possible melting of the cathode HIPIMS (High Power Impulse Magnetron Sputtering)
HPIMS Typical voltage and current trace from a high power pulsed magnetron discharge. Example of a duty cycle.
HIPIMS – Characteristics Pros: • Smoother thin film surface • Very good film adherence to the substrate • Possibility to coat complex geometries • Possibility of self-sputtering and resulting removal of defects and impurities Cons: • Low deposition rate
