VERFAHREN ZUR SPUTTERBESCHICHTUNG VON OBERFLÄCHEN

摘要

Described is a method for coating surfaces using a facility having sputtering electrodes, which has at least two electrodes that are spaced apart from one another and arranged inside a process chamber, and an inlet for a process gas. The two sputtering electrodes are acted upon by a bipolarly pulsed voltage in such a way that they are alternately operated as cathodes and as anodes. In addition, the frequency of the voltage is set between 1 kHz and 1 MHz. Furthermore, and that the operating parameters are selected in such a way that in operation, the electrodes are at least partially covered by a coating material.
