  • Patent number: 9111999
    Abstract: When performing plasma assisted etch processes for patterning complex metallization systems of microstructure devices, the probability of creating plasma-induced damage, such as arcing, may be reduced or substantially eliminated by using a superior ramp-up system for the high frequency power and the low frequency power. To this end, the high frequency power may be increased at a higher rate compared to the low frequency power component, wherein, additionally, a time delay may be applied so that, at any rate, the high frequency component reaches its target power level prior to the low frequency component.
