Radio frequency (rf) ground return arrangements |
| abstract |
A radio frequency (RF) ground return device is provided that provides a low impedance RF return path to RF current in a processing chamber of a plasma processing chamber during processing of a substrate. The RF ground return device includes a set of confinement rings, the set of confinement rings being configured to enclose a confined chamber volume configured to maintain a plasma that etches the substrate during substrate processing. The RF ground return device also includes a bottom electrode support structure. The RF ground return device also includes an RF contact enabled component, wherein the RF contact enabled component includes a set of confinement rings to facilitate a low impedance RF return path to return the RF current back to the RF source. An RF contact is provided between the lower electrode support structure. |
