Abstract
A rotary sputtering cathode assembly is provided that comprises a rotatable target cylinder having a first end and an opposing second end. A first power transfer apparatus is configured to carry radio frequency power to the first end of the target cylinder, and a second power transfer apparatus is configured to carry radio frequency power to the second end of the target cylinder. Radio frequency power signals are simultaneously delivered to both of the first and second ends of the target cylinder during a sputtering operation.
