High-power impulse magnetron sputtering (HiPIMS) systems have been previously studied with mid-frequency (MF) plasma excitation, utilizing the “off” period to enhance the deposition rate, decrease the working pressure, and improve HiPIMS plasma generation. Our latest application note looks at the time-resolved ion velocity distribution function (IVDF) in a high-power pulse plasma in three modes of excitation: pure HiPIMS, medium-frequency pulsed bipolar (MF 350 kHz) and hybrid pulsed HiPIMS + MF.

Click to read the new Theory of Operation for our Semion System. This highly versatile instrument measures ion energy, ion flux, negative ions, temperature and bias voltage at any location inside a plasma reactor, even at the substrate position. The multi-sensor version can also be used to look at uniformity issues that are very common in plasma processes. This gives valuable and unique data to many industries including etching, deposition, ion beam and space plasma.
