Abstract:
1. A method for treating one or more articles with a selectively extended and concentrated plasma generated from dissociating one or more gases, the method comprising: supplying one or more gases from a source to a first chamber; applying RF power to dissociate the one or more gases and create a plasma; withdrawing the dissociated one or more gases from the first chamber through at least one RF grounded pathway, wherein the at least one RF grounded pathway is electrically grounded and includes at least one conductive coating on a surface of the at least one RF grounded pathway and the at least one RF grounded pathway passively and selectively extends and concentrates the plasma in the at least one RF grounded pathway; and supplying the dissociated one or more gases to a treatment chamber containing one or more articles.
