Abstract:
1. An apparatus for processing a semiconductor substrate, comprising: a processing chamber having a chamber body; a substrate support disposed in the processing chamber and defining an upper portion of the processing chamber and a lower portion of the processing chamber; a lid assembly coupled to the chamber body, the lid assembly comprising a conductive gas distributor coupled to RF power and a powered electrode insulated from the conductive gas distributor, wherein the powered electrode is disposed between a first insulator and a second insulator, wherein the first insulator insulates the powered electrode from the conductive gas distributor, and wherein the second insulator insulates the powered electrode from the chamber body; and a shield member disposed in the lower portion of the processing chamber, the shield member being positionable inside the processing chamber by an extension of the shield member outside the processing chamber.
