摘要
Systems, methods, and apparatus for processing a substrate in a plasma processing apparatus using a variable pattern separation grid are provided. In one example implementation, a plasma processing apparatus can have a plasma chamber and a processing chamber separated from the plasma chamber. The apparatus can further include a variable pattern separation grid separating the plasma chamber and the processing chamber. The variable pattern separation grid can include a plurality grid plates. Each grid plate can have a grid pattern with one or more holes. At least one of the plurality of grid plates is movable relative to the other grid plates in the plurality of grid plates such that the variable pattern separation grid can provide a plurality of different composite grid patterns.
