Abstract
In a plasma processing system, a method of reducing byproduct deposits on a set of plasma chamber surfaces of a plasma processing chamber is disclosed. The method includes providing a deposition barrier in the plasma processing chamber, the deposition barrier is configured to be disposed in a plasma generating region of the plasma processing chamber, thereby permitting at least some process byproducts produced when a plasma is struck within the plasma processing chamber to adhere to the deposition barrier and reducing the byproduct deposits on the set of plasma processing chamber surfaces.
