Description | A new method to control whether a radio-freguency (RF) reactive sputtering deposition processes runs in a pre-adjusted experimental conditions was proposed. The frequency spectrum of the cathode voltage and of the voltage on an uncompensated probe immersed in the plasma was measured and it was proved, that some of the harmonics are extremely sensitive markers of the transition between the metallic and the compound mode of the RF sputtering. |
