1 sputtering variable 1.1 Voltage and Power If the applied voltage is changed within the pressure range where the gas can be ionized, the impedance of the plasma in the circuit will change accordingly, causing the current in the gas to change. Changing the current in the gas can create more or fewer ions that hit the target to control the sputtering rate. In general: increasing the voltage increases the ionization rate. This will increase the current, so it will cause a drop in impedance. When t... read more
