Abstract:
Systems and methods are presented for a peripheral RF feed and symmetric RF return for symmetric RF delivery. According to one embodiment, a chuck assembly for plasma processing is provided. The chuck assembly includes an electrostatic chuck having a substrate support surface on a first side, and a facility plate coupled to the electrostatic chuck on a second side that is opposite the substrate support surface. A hollow RF feed is configured to deliver RF power, the hollow RF feed defined by a first portion contacting a periphery of the facility plate and a second portion coupled to the first portion, the second portion extending away from the chuck assembly.
