Abstract
A comparison between the deposition rates from a copper target in a diode sputtering system using either rf (13.56 MHz) or dc power shows that the deposition rates are the same for equal powers. In situ measurements of the temperature difference, ΔT, between the inlet and outlet target cooling water support this observation. These results contrast with those of magnetron sputtering, where the deposition rate is substantially different for rf and dc power sources.
